Hi All, It's been awhile since my last post, so I thought it was time I made another. I have been in receipt of a BB12VB-RED recently! Ahem, probably more like a year or so ago. As you can see from the photos, one of the pickups is very damaged… Another Eurobrick member, Alainneke, had already kindly made some replacements out of brass… I had sent him the diagrams of the pickups in AutoCAD, and extremely excellent reproductions were sent as a test in return. At the time I’d only opened my 'teenaged' black motor, as seen in photos, and the new brass pickup studs were supposed to be destined for it… The RED 12V motor is very, very rare, I have held back on using the replacement pickups until now… I am glad I have waited though, my apologies Alainneke! After reading VGO’s suggestion in post http://www.eurobrick...pic=50345&st=25, post #28, I tried the idea out on a black motor and it moved during the operation and I snapped a tab off the end, see pic. So I decided to build a jig out of Lego to hold the motor. The top part of my jig is real Lego, while the bottom is entirely made of Fako(Fake Lego) due to my needing to augment some of the pieces to fit the underside of the motor and wheels. I used MEK(Methyl-Ethyl-Ketone) to ‘weld’ the pieces together, along with some small strips of a smooth(no embossed numbers) credit type card, see pics. Okay, My advice is that you try and run a razor blade around the circumference of the bottom of the motor, hopefully using a ‘jig’ like shown. I do mean “Razor blade” as a “Stanley” knife blade will do the damage that I have shown in my earlier openings, try a ‘BIC single blade’… Making and using a ‘BIC’ single razor blade… I used the razor whilst the motor was in the top part of the jig. Once in the jig, use a 2.5mm rod/nail and hammer in both power plug holes, to gently persuade the bottom to come loose on either side. Seat partially opened motor on the ‘bottom’ part of the jig, and use the remainder of the credit/shopping card to gently hammer down on the wheel axle to pry the last of the plastic welds apart. The motor is now broken open… Here are some pics of the open casing with the old and new pickups, I will update the post after I have cleaned up the motor parts. If for whatever reason you need to take a wheel off, I.e. for cleaning excessive hair/crud in sleeve bearing, then you start by removing the cir-clip next to the sleeve bearing. Move bearing nearer to gear cog, then gently pries the cylindrical spring clip out of the wheel in the same area as the hole in the wheel. When you're cleaning the parts inside, be careful with the metal part 'A'. There are two small hardened steel discs that sit either end of the spindle, only the dirty grease is holding them in.... Now it's time for reassembly and re-greasing...

MOD - 12 volt wheels with axle hole for Power Functions motor
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, since 7777 book came out, I've always wanted to integrate Trains and Technic worlds. Back in the 80's the problem was the complete lack of train wheels with a Technic axle hole. It was solved with RC trains a lot of years later. Therefore, I can convert a 9v train to PF without too many problems (aesthetically speaking). But for 12V trains it is different. Wheels are made in a specific way, they have the hole for connecting rods, they're more "fat" than RC/PF wheels. Frankly, I do not like 12V trains converted to 9V/PF standard bogies. But I like the PF motor, its speed, the possibility to increase speed gradually...and the fact it keeps the central hole for third wheel. So, in these years I repaired a lot of 12V motors...and some were really in bad shape. Look at the right wheel, it is completely destroyed inside. So I decided to try to implement my solution to connect standard, intact 12V wheels to technic axleholes (which I do not list here, since it was not satisfying). First, I got a standard Technic bush, and cut it a bit. Then I put it inside the damaged wheel hole. It fits fine, but needs to be glued. Once glued, it is time for some testing. The 6-long axle goes right in - but the red ring coming out from the wheel is too thick. So I prepared another wheel (gray bush). This time I cut the bush a bit shorter and fits right. The 5.5 axle is perfect , so I'll need to cut two 6-long axles to the right lenght. And this is the result - this is my 7740 no°3, totally converted to PF. It works fine, but as you all can imagine, it is all made by hand and bushes are not machinery-centered. Therefore the locomotive is not stable as I would like. For the moment, better than nothing! -
So far, only ONE AFOL has given me the right answer :-) Hi everybody, This one is a real challenge! After the quiz N2 that we had as warm-up, here we are with a harder quiz. I am really curious to know if anybody knows or can find the answer of this one. I would consider a prize for the winner(s). If you are sure you know the answer, please "DO NOT SPOIL", but only pm me. But if you have any guess together with some reasons for your guess, you are very welcome to comment under this post so that we can discuss about it and who knows, maybe we get multiple responses. Here is the question: WHICH INSTRUCTIONS have MORE THAN ONE VERSION? The sets in question are 7710, 7715, 7720, 7722, 7725, 7727, 7730, 7735, 7740, 7745, 7750, 7755, 7760. I believe you cannot find the answer by googling (I couldn't). Good luck :-)

I have seen two variations of instructions 7860: 1) For the second release 1982-87, the code of instruction is 113483 ©1981. In the instructions, we can see this variation of "Straight Conducting Rail with Rail Interruption" 3242apb01: https://www.bricklink.com/v2/catalog/catalogitem.page?P=3242apb01&idColor=9#T=S&C=9&O={"color":9,"iconly":0} 2) For the third release 1988-94, it is 120622 ©1981 in which we can see this variation of "Straight Conducting Rail with Rail Interruption" 3242bpb01: https://www.bricklink.com/v2/catalog/catalogitem.page?P=3242bpb01#T=S&C=9&O={"color":9,"iconly":0} 3) What about the first release 1980-81? Is there any instructions for it (do you have it?) in which we can see "Straight Conducting Rail with Rail Interruption" 3242a: https://www.bricklink.com/v2/catalog/catalogitem.page?P=3242a&idColor=9

Request for technical advice: 4.5V battery box, 12V conducting rail
DameVeraLynn posted a topic in LEGO Train Tech
Having spent the last few days restoring some of my childhood Lego trains, I've run into a couple of problems which I hope the experts on here may be able to help me with! 1. 4.5V battery box (BL Item No: x488c02) This particular box comes from 7722 and was originally used to power a 4.5V train motor. The motor still works (I have tested it by connecting it to the 12V transformer with the control knob inverted) but it fails to run when connected to the battery box (filled with three brand-new rechargeable C batteries). Does anyone have any troubleshooting advice for these battery boxes? Can you suggest what steps I could take to try and get it working again? Any thoughts on the best substance to use to clean the contacts? 2. 12V conducting rail (looks like BL Item No: 2731b) This rail should transfer power to the track when connected to the 12V transformer, but fails to do so. I've tried unscrewing the plug and replacing it with another, but that doesn't help. Rather strangely, it also cuts the circuit when added to a loop! My suspicion is that there's an internal fault, possibly caused by corrosion (it looks nice and clean, but I spent some time rubbing it with a model railway cleaner before testing it!) Has anyone come across a problem like this before? Many thanks in advance for any help you are able to provide! -
Hi there, as most collectors know, the grey era boxes were redesigned in 1989. But I don't know if all sets from the 1989-1990 lineup were affected, therefore I need your help. So far, I found 1989 versions of the following sets: 7813 Shell Tanker waggon (sorry, no picture yet) 7817 Crane Waggon all sets from 7850 to 7861 7865 Motor 7867 Light posts The 1989 version can be recognized by looking at the copyright date, which contains two years: the first one states the initial release (e.g. 1980, 1983 or 1985). The second year is always "1989". [7864 power supply is a special case, it exists in three different box versions: 1980 and 1982 without copyright, and the final one with 1990 copyright] So, the question is: do the following sets also exist in a 1989 version? 7823 Container crane depot 7835 manual road crossing 7839 car transport depot 7866 remote controlled road crossing If any of you has one of these sets with a 1989 copyright, a picture would be great. kind regards, Christian

MOC - Three axle passenger wagon for 12v / 4,5v trains (Umbauwagen 3yg)
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, this evening I prepared a wagon which was in my mind for some time, but I've never built. @jtlan mentioned it in the "castering effect" thread, showing us his two very nice Umbauwagen 3YG, which are built with new parts. Since these wagons are the perfect partners for DB BR78 locomotives, I tried to replicate it in gray era style. It is very simple and straight: the narrow part where the doors should be was not replicated interiors are similar to the 7725 undercarriage is quite simple - since it must leave space to the passive steering system I added a toilet, since it was a nice challenge. It does not have a door in the photos, so the toilet is visible. After some passengers complained, I closed the door. Steering system is very basic, and it leaves space for interiors (I just noted that the two red parts have "Pat Pend" markings - my 60s collection will be happy) . The only part not used in the gray era is the 6x24 train base. It can be made of plates, but I have a lot of them - and this is a good use. I cannot use the green color, but I saw the Umbauwagen was also made in blue as a wagon-lit. Here it is with my 12v BR78 and 7820 . Hope you like it! Ciao! Davide -
Hello everybody, On Page 5 of this brochure from 1991, it is mentioned: http://worldbricks.com/en/catalog-year/1990/catalogs-1991/1991-lego-catalog-2-en-fr-nl.html For owners of 12V Lego trains, a special 12V train brochure is available. Please contact Lego Spares service. Aux utilisateurs de trains Lego 12V: Réclamez la brochure special "trains 12V" a Lego S. A. ... Please let me know if I can find in internet and download the special 12v train brochures from 1991, 1992, 1993 (or even from 1990, 1989, 1988). Otherwise, iIf you have them, I really appreciate if you can scan them or just let me know, so that I can find a way to borrow them from me, or even buy them. This is for a longterm project for improving the current inventory of 12v and 4.5V trains on bricklink. One concern is the service bag 5086, which is declared on bricklink from 1993, but I am not sure. I cannot find it in any brochure available online! Cheers

[MOC] Dual-voltage (9V-12V) GySEV Vectron locomotive
Ashi Valkoinen posted a topic in LEGO Train Tech
Hello all, I'd like to introduce my latest MOC, the Siemens Vectron locomotive of GySEV/ROeEE railway company. These locomotive appeared only months ago on Hungarian rails, the Austrian-Hungarian railway company, GySEV/ROeEE bought 9 of these with different equipment. Some of them are dual-voltage and run under 25kV, 50Hz (Hungary) and 15kV, 16.7Hz (Austria), some of them are capable to work with DC supply as well, and 2 of them with the two different AC-supply will get diesel units inside to ensure the locos can move on industrial tracks not electrified at all. When these locomotives started to appear I designed it in LDD, there was a little competition between Hungarian LEGO train fans with the design. I was the first who finished the virtual build and I loved it, so I decided to build it as soon as possible. This was the first versions, but only AC-DC locomotives have 4 pantographs, the AC-only types have only two of them. I'm quite proud of the angular green tile in the side pattern and also the angled front needed a little thinking around. I started to love the old hing plates with two and three teeth - these teeth do NOT brake the line of the hinge plate and the whole LEGO part fit into less space and easier to build other things on the top of these bricks. The slots for lights are also capable of to be lit by LEGO LED lights - another good invention introduced first in my Stadler FLIRTs to use the flexible exoforce tubes which are capable of bringing the light of PF LEDs where I need that light. You may ask why is that M-motor hanging around - it has a great importance in this model! As the real thing with two different AC-supply, my Vectron works under two different LEGO-voltages - it is compatible with 9V track and 12V track as well! The M-motor switches a polarity switch brick, which cuts off 12V pickups from 9V train motor's contacts - when the locomotive runs in 9V mode, the pickups for 12V track could touch the same rail when going through 9V points, and the loco could short circuit herself! When the loco runs in 12V mode, the polarity switch is ON, and the 9V train motors are supplied from 12V track. At the other end of the locomotive there is an another M-motor - it cuts off the 9V train motor from the output of the controlling SBrick - it won't be a wise idea to power that SBrick both from battery box and both from the 9V track, through its output... Look at the next image, how it works: So if the locomotive reaches the end of electrified track (12V or 9V), it still can carry her train forward - it can run on internal battery box as well. And finally, yes, these stuff did fit into the model: (Since the lower light on each side serves as red and white light on the real thing and upper slot serves for long distance lights at night I put white lights on the upper, red lights on the lower slots.) Also some other images and further details can be found in Hispabrick Magazine #29: http://www.hispabrickmagazine.com/sites/default/files/Descargas/HBM029_ENG.pdf Comments and critics welcome!

Message to all "hardcore" collectors of the grey 12v train era 1980-1990
Carrera124 posted a topic in LEGO Train Tech
Hello, when I started collecting the sets from the grey 12v era 1980-1990, I bought many used sets and incomplete lots. Bricklink was (and is) a great help to check them for completeness, and to complete the missing parts. But later on, I faced some problems, e.g.: 1. I found part variants, that Bricklink doesn't know . 2. Some invetories are obviously wrong. For example, it is hard to believe that the power rail 2731a shall be contained in set 7725, but not in 7727. In reality, it looks as if this part wasn't used at all before 1986. 3. Alternative parts are not consistent among various sets. For example, the second version of the black steam cylinder x461 is listed as alternate part for 7730 and 7750, but not for 7865. I got into conctact with other collectors (e.g. Reza) and we exchanged lots of pictures and information. The result is a huge table that can be downloaded here: Table It is a write-proteced Excel file. To use the file, you need a monitor with huge resolution (at least Full-HD) and not too big scaled font size (for Windows, 100% is fine). The table shall be a basis for discussion, not a final document. In many cases, there are only hints and conclusions, but no hard evidence. Any feedback is appreciated. A short guide to the table columns: A "Part" Basic part description B "Variant Type" The different known variants of the part. C "Number" Bricklink part numer. Parts that Bricklink doesn't know, use a "+" at the end of the name, or ar marked "?". D-N "Years" Assignment of the part variants to the years of production / selling. O-P etc. "Sets" Each set consists of two columns. The first one indicates, if the set does containt the part at all. The second columnt indicates, how many parts are contained, and if it is a "regular" or "alternate" part. P.S. I already had contact to the Bricklink inventory admins. They are interested in improving and consolidating the set inventories. But for me, the process is extremely complicated and time-consuming. Every single change for every single set should be handled as separate "inventory change request", and every request takes weeks/months until a decision is made. Imho, this is very ineffective, so I decided to write this text and to provide the table for download. -
Hello again, I am looking for instructions of 753, 754 and 755. Didn't find them online. Do you know from where I can download them or do you have them?

Hi all, I'd like to present you my first 12V MOC. It is a Deutsche Bahn BR78 - inspired locomotive, built using extra pieces from a 7730 and 7750. This is the third big steamer I use, along with the original 7750 and the 7777 steam locomotives. I built this one following using special pieces (e.g. lights lenses are yellow/clear like in 7750 - rubber pipes on the sides) and following the style of the early 80's Lego trains. It was simplified in many details, like the cabin (using standard doors and windows) and sides (which are missing a lot of leverages, handrails and so on). Here it is on my test station - front and rear lights are on when moving forward, small white light on the back is on when moving backwards. Hope you like it!

What trains could be rereleased if Lego goes the Legends route?
Doom2099 posted a topic in LEGO Train Tech
I am so excited with Lego's news about their reselling the Taj Mahal, because there's always the possibility that this is just the start of something big, and we could be getting an affordable chance to buy classic sets that we missed out on, or don't want to pay the current online prices. I remember with the arrival of the internet how cool it was to go to places like Lugnet, and then to Ebay, and being shocked at how much trains had gone up in price, even just from 1980 to 2000. Then after everyone complained online about how they missed out on the Metroliner, it suddenly reappeared like a legendary phoenix. With the Club Car in tow! At the time, it made perfect sense bringing back the first 9v train while 9v was still going strong. 10 years seems to be the magic number for rereleases with Lego, as seen with the Legends line, and now Taj Mahal. So I was wondering, what if any trains do you think Lego could/should rerelease? Could they take old 12v and 9v sets and swap in Power Functions? What about the Train Shed, or Santa Fe Super Chief? Emerald Night? Are there any regular retail trains sold after 9v that people are clamoring for a return of, as we saw with the Metroliner almost 20 years ago? Is a train related rerelease even feasible with Lego today? I would love to hear what others think is possible / desired. Personally I wish I could buy more Santa Fe cars for regular retail price! -
Hi everybody, I have been carefully watching all trains 7730 on sale in different countries since summer 2017. At the beginning, I realized that the 3 * yellow cones listed in the inventory in bricklink had axle hole: https://www.bricklink.com/catalogItemInv.asp?S=7730-1 The yellow cones 3943a: https://www.bricklink.com/v2/catalog/catalogitem.page?P=3943a&idColor=3#T=C&C=3 This yellow cone 3943a appears in two sets. 3 used for the train 7730 and 2 used in 599-1. But many trains had the other version 3943b with axle hole: https://www.bricklink.com/catalogItemIn.asp?P=3943b&in=S This version is used in two sets. One used in 4982-1 and 2 used in 6954-1. Lego produced both versions since 1979. But there are some doubts on this. Sets in which 3943a appear are produced in 1979, 1980 and 1981 (msotly). This suggests that sometime about 1981-82, Lego replaces 3943a with 3943b. The train 7730 was produced from 1979-82. Then probably, some sets made in 1982 came with 3943b. About one third of the trains i have seen have the version 3943b. As the two versions are as rare as the other, I simply conclude that Lego released some of them with 3943b. It is not likely that so many private sellers lost all the three yellow cones 3943a and then bought or found the other version 3943b and replaced with them. Thus, if you bought this train in your childhood and still have it, could you please comment which version are your yellow cones? If you still have the box, could you check if it is D/F/NL or UK/F/I version? It its also helpful if you tell from what country the train was bought. For learning about different versions of box, see: If you could attach a photo of your train, box(the language part on the right side of the front box) and cone, it would be great and helpful. Also, a photo of the bottom of the motor, if you are sure that the red motor is not switched with another one. Reading the number on the bottom of the motor, we can see in what year it is produced. Here is mine where you can read 38 0 which means week 38 year 1980: This will help me to come up with more evidence to submit a change of inventory request. Regards Here I put some the trains on sale, now or before coming with cones 3943b: https://www.ebay.co.uk/itm/202086086008?clk_rvr_id=1385696026058&rmvSB=true http://www.ebay.ca/itm/Rare-boite-Lego-TRAIN-7730-briques-neuves-jamais-jou%C3%A9/172901510590?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649 https://www.ebay.it/itm/152813017599?ul_noapp=true http://www.ebay.ca/itm/Lego-Eisenbahn-12V-12-Volt-Dampflok-G%C3%BCterzug-7730-mit-BA-OVP-komplett/263014487777?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649

A few days ago, I made a decision. I've tried to build big houses, buildings and trains and have never been satisfied. I and new pieces and colors doesn't match and when I am collecting 12v trains and buildings and was a kid in the 80s it was actually a pretty easy decision: My mocs will look as they are taken from a LEGO catalogue from 1982-86. So, here is my first try. The brand new 7833 Shell terminal from 1984! It's still only build digitally, but I think I'm going to buy the pieces to build it in real, too! Any ideas and thoughts are welcome. Be mercyful :-) http://tydje.se/lego/7833/7833-2.jpg http://tydje.se/lego/7833/7833-3.jpg

12v trains in alternative colours - looking for some inspiration
exstatik posted a topic in LEGO Train Tech
Hi guys, im looking to build some 12v models in alternative colours. E.g. 7745 in all black or 7755. Looking at Bricklinking cheaper parts. Wondered if anyone had some pictures they may have of stuff they had done for some inspiration? Thanks in advance and I look forward to hopefully seeing some of your creations. ? -
As the title says really. Has anyone created anything like this? Would love to see them if so. Same goes for the other way round too. I've seen a nice long base 7710 carriage before on here. Look forward to seeing anything you've created along these lines!

Hi all, Does anyone have experience/ knowledge of using another type of cabling for 12v layouts and accessories other than the official Lego stuff? I'm looking for a cheaper alternative for long stretches of cabling. Thank you very much! ?

[Train Layout] The WindMill Lego Train Layout Project (WMLTL)
LegoLow posted a topic in LEGO Train Tech
Hello everyone, for those who do not know me, I'm a big fan of trains and especially Lego Train. I finally have a space to create a Layout finally worthy of the name. My approach comes a little more of the model in the sense that I like to see a train pass over another, to automate the network, make realistic through light signals, station stops, etc. ... I started this project in February 2016 in my basement where I made by myself, furniture and shelf for storing SET Lego but also to design the layout. I was already well advanced when an incident occurred: the flooding of the basement end in May 2016 .... Then in August, the discovery of a leak in the water supply of the house forced me to completely dismantle this first try of a Layout to access the water inlet pipe ..... I come back now in force therefore with a first experience, many tests on the possibility for our pretty trains to climb slopes (straight or curved) to optimize the best of my available space and create a nice layout ! ;-) Due to financial limits, this layout will be not made with 100% of Lego, I will use wood and homemade stickers, custom electronic to make it. Here are the first shots (or I should say the nth plan because with Bluebrick, we never stop to change those plans) to my future Layout (so different from the first that I had designed and unfinished) WMLTL - v5 - Level 0 by LegoLow, sur Flickr Corresponds to trainyard + walkway + a brief passage of the 12V track WMLTL - v5 - Level 1 by LegoLow, sur Flickr Ground level with his future main station WMLTL - v5 - Level 2 by LegoLow, sur Flickr First level of the "mountain" : secondary station and then, possibility to climb in the mountain or to go back to the main level WMLTL - v5 - Level 3 by LegoLow, sur Flickr WMLTL - v5 - Level 4 by LegoLow, sur Flickr WMLTL - v5 - Level 5 by LegoLow, sur Flickr Top of the mountain.... Finally a view (done quickly, I will improving later), global superimposed, giving the idea of what will be hidden, visible .... WMLTL Project - v5 by LegoLow, sur Flickr Following probably next week with the start of the implementation of Level 0. It's a big challenge for me because this project is made of mixing differents things : LEGO, electronics, electricity problematics, Priority management on a network, etc.... Hope you will find that interesting to ! -
Hello Guys! I am trying to find grease in America that would be safe to use on Lego 12v motors (from the 80s) without paying horrendous prices. I am wondering if anyone has found suitable grease in the U.S. I have had a few people tell e about ROCO 10905 but that would be $20 to have it shipped over here from Europe. Thanks -RailCo

Hello, I am reaching out to all 12v train users. I recently purchased and received a 12v train (the 7725). Unfortunately the motor is dead, I put it on the track after building the whole model and setting all the track up to find it not moving. At first I thought maybe if it hadn't run in awhile it would need a little help. That didn't work so I tried it by just connecting a wire to the motor itself and gently moved the wheels. The motor started to produce a light smoke so I immediately shut the power off and haven't tried anything since. I did see some life though at one point, it did move about 1/16 of a turn at best and I could hear it trying to move. If the seller is cooperative hopefully I can work something out with him. If not I was hoping many people on this forum could lead me in the right direction. Here is what I know about the motor: It looks to have been opened before. It is the version with the separate bogie pin. From what I can see there is some hair spun around the axles. I am wondering if I need to completely give up on the motor or if there is a way to fix or replace just the motor inside. I am really lost and would love any help that someone could give me. I looked for awhile but I haven't found a post about someone having the same problem as me. Even if someone has a broken lego casing for the motor but there electrics still work I could be interested in that as well. Thanks, -RailCo

Hi All , just signed in to this forum cause I was wondering about something .... I'm into the 12 volt train system again and was wondering about modified 12 volt track . Hs anyone done some modifiyng on tracks , switches ,etc. ? Here's some pics of my own creations untill now... A half straight track with original contacts a point prototype with same angle as 2 curved rails Let's see what you guys have !

Hello! Going through my parent's attic over xmas I rediscovered my old 12v train set, which I'm now trying to restore and get working again. After cleaning up a bunch of contacts with WD40 the actual train and power brick work, which is nice. However the remote control for the signals seems to be completely jammed and neither button will actually move. Has anyone successfully repaired one of these? I can't even see how to take it apart without breaking it. Thanks

Hi! This is my latest MOC. It's a pf 7760 that runs on pp3 (9v) battery with a custom adapter. Since i don't have the 7760 i built it with all kinds of colors (it is a prototype after all). Here is the pp3 battery. I wanted this loco to have the iconic 12v clicking , so i put a little metal tab between the motor and some bricks. Here it is in action with the custom clicking sound. The rear with the ir receiver. And here it is .
