[MOC] The Milwaukee Road EP2 Bipolar E-2 - in 12V style
Paperinik77pk posted a topic in LEGO Train Tech
Hi all and Happy New Year!!! Since I'm waiting for H0 parts to arrive to continue my experiments, I am browsing the Internet a lot to get some inspiration. Searching for some American locomotives I found (again) the Bipolar, a locomotive which I like a lot...but I always end forgetting its name. I recall the GG1 in my mind...but the name Bipolar name simple does not fit into my 64kb of memory (38911 bytes free)! So, I thought it could be nice to try this big lady in 12v, just for fun. In this case, I built the E-2, the lattest rebuild of one of the Bipolar family, made in 1953. It's a massive thing, and the two motors will surely be helpful to move the locomotive and the Hiawatha train (I did not design the wagons, but for sure they would be...heavy!!!). As the original E2, the locomotive has asymmetric details on the two "big noses". The colors are WRONG - yellow should be orange, black should be dark gray, so I kept a 7740 paint scheme, well suited to the color range available in the 80s. As any high-end locomotive it has some expensive parts (all the windows). One note - the 2x2 windows can be also in old gray (from 7740), a bit cheaper option. The locomotive has 6 point of articulation, I think it could manage the R40 curves - my real life DB BR78 is less articulated, just to made an example. As you can see, the whole body seems a bit taller than normal 12v trains, but all in all, the real bigger details are the two pantographs. I don't think I'll ever build it in real bricks - for the only reason that I'm not so convinced to see it going around R40 curves. Maybe it could be a good shelf queen I hope you like this one! Ciao!

[MOC] Lego DRG V3201 - Diesel/Pneumatic Locomotive - in 12v style
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, always starting from this inspiring discussion... ... @Reker1000000 introduced me to a very particular locomotive: "DB V3201 seems like it would be an interesting starting point for a locomotive to model in 12v style with the red motor..." The locomotive we're speaking about is the DRG V3201, one of the first experiments to upgrade from steam to Diesel engines. In this case, Diesel motors were available , but problem was related to transmitting their power to the wheels. Gears were too weak, Hydraulic transimission was still in development...so the idea was to replace steam with compressed air, therefore maintaining the "old" transmission system (including distribution) used by steamers. In short, it worked this way: DIESEL ENGINE --> COMPRESSOR --> RESERVOIR -->CYLINDERS --> COUPLING RODS --> WHEELS More or less what is seen in some Pneumatic locomotives made in Lego (great stuff!) with electric motors. Well, seems great, but there were many problems related to the heating of compressed air, its cooling (!) and cylinders lubrication - all for maintaining its efficiency. Here's an interesting link! http://www.douglas-self.com/MUSEUM/LOCOLOCO/diesair/diesair.htm All in all - a very complex hybrid system, with many gaps to be solved with engineering "patches". But it's a cool locomotive and making it in 12v style could really be a challenging task. First of all, it's the most asymmetric thing I've ever seen , second - it's a very tormented design - which cannot be captured fully in 12v style, due to lack of parts at the time. It's however a very peculiar locomotive (depicted also in a postal stamp!!!) and it's worth to be tried. Here it is, just out of the shed , helped by a small V60. In reality, this event could not happen, since the V3201 was scrapped many years before the launch of the little shunter, but since we can do whatever we like with our fantasy, I was more optimistic and imagined a restored V3201 ready for some hystorical train! The V3201 is based on the chassis of a BR78, which - luckily - is one of the 12v locomotives I've already tried to create. Therefore, chassis was already prepared and only needed to be adapted to the longer body. This big beast has a quite boxy body, which seems to be made soldering together some parts of cabins, cut from steam locomotives. The central part of the body is sticking a bit out from the overall shape, and this is due to the big submarine diesel and air reservoirs. The main charachteristics are the two big gray radiators, the small windows on the corridor side, and those big stairs. Stairs were a nice thing to replicate, even if these are not the same as in the prototype. I did not use the big train doors, since these did not allow me to recreate the stairs and handrails. In the real thing, the stairs go over the cylinders, so using the 12v standard ones was quite a mess. I replicated them with normal parts. and this was not a problem. I had however to "cut" the stairs in half, the upper one being fixed to the body, while the lower one being part of the bogie (and turning accordingly). With the 12v motor, this design needed to be somehow adapted. On a real 12v motor, the central hole can accept an half Technic pin. Using a normal Techic brick some plates and tiles solved the problem. The ladder is kept in place by the pin and "slides" together with the motor. Between the radiator and the cabin there's a small, virtually transparent door since it's made of a panel full of small holes. The body in reality should be 4-wide in that point. I tried fences, door fences, everything did not fit and SNOTting was quite impossible (for me at least), given the limited parts available. Even Marklin's model is solid in that point, so I concentrated more on having at least a grille pattern. Using the ladder part was not so nice, it was just confusing. I therefore tried the just seen @zephyr1934 technique (thanks to you and Katy!), to have some visible horizontal lines. I used 3794b parts (jumper) . It works also with normal plates, but this is way better. Doors features a possible, even if not used at the time, SNOT for the door hadle, using headlamps bricks. Here's a shot from above, showing the 7-wide central part of the locomotive. As you can see I played a lot with the jumpers parts. And here's the "blind side" of the locomotive there's not so much to say ,being pretty smooth! Apart big red wheels and red motor, 2x1x2 and 1x1x2 black windows are there, just to remember there's some 7730s and 7750s blood inside the veins of this "thing". Here is visible the big radiator... ...and here is visible the smaller one. Looking better at the central headlight you can see some "white stuff" between the bricks - it's the classic 12v light brick with the addition of a small diode. This old trick allows the headlight to be lighten up according to locomotive's direction. Radiator is made by 1x1 plates, trying to replicate the "pattern" of the real thing. I put here red lights in 7777 style, even if these should be white, according to prototype. A brief mention to the Shed - it's an old MOD - I do not sincerely remember if I already presented it here in Eurobricks. It's a 7777 build, converted to a more shed-looking thing. Since I like to replicate dioramas in 12v style, this could be a nice addition to the overall scene. I hope you like it! Thanks again to @Reker1000000 for his inspirational idea! Ciao, Davide -
Hi all, this time I propose a real build, it's not completely new - many of you surely has seen it in some of my digital renderings, but was never built. I finished it yesterday, when the red motor finally was repaired and the missing rare 2x2 black window arrived. To create this one, my third copy of 7810 was used as donor for the baseplate and black windows. So I decided to keep the 7810 number when I chose the stickers (the renderings have 7730 decals). Just to explain, all my MOC locomotives keep numbering of original Lego sets from which are derived in terms of parts. To celebrate its arrival, I used my small 12v test track. As you can see is a very simple build, standardized in 12v style adding the black side doors (absolutely not present in the prototype), and 5 2x2 black windows. The red motor was a must- I tried to use the black one - but it wasn't the same thing!!! This motor was not running anymore, so I bought a black one in bad aesthetic conditions as donor. I removed the electric motor from black shell, cleaned all inner parts, reinforced the red shell internally with some superglue (it had some cracks), changed axles (using the ones from black motor) and performed a test. Once the test was ok - I finally glued the two parts of the red shell. Even if the chassis is common to other locomotives, it seems very small. The inside is small aswell, and I only could fit a lever in 7750 style. You can see the 12v light brick and its cables. I bought some 12v light microbulbs - maybe I will succeed to light up also the rear headlight when going in reverse. Even if it has no weight bricks, it still has a decent pulling power and runs fine with small wagons. Now it needs its own set of cars. I hope you like it!!! Ciao, Davide

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
