http://P1110591 by Simon Jakobi, auf Flickr To be honest this is my 6th version of the german crocodil. Now she shares the drivetrain with her swiss sister. Each truck is powered by a PF-L-motor. All axles are driven. The third and fourth axle are blind. Therefore the trucks are completly new. I also worked on the fronts of the noses and the shape the roof. I hope, you like the result!

[MOC] Lego DB BR80 12v - in Torben Plagborg style (8-wide)
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, since I read the very, very interesting thread about Torben Plagborg creations, I've been trying some new designs (some are just sketches, just to understand how things could work). Now, in this nice thread some nice 12v creations can be seen - but one captured my interest more than others. It's a little blue steamer with a black 12v motor. It seems pretty big, so I'd say it was an 8-wide experiment. In general, all the top shelves are very interesting. Starting from that little steamer, I began to think about a 12v locomotive in 8-wide. So I started designing another small steamer (I'd say a well known prototype): the great Deutsche Bundesbahn BR-80. 8-wide is not a common scale for me - I only tried it two times in my whole life, so it was a trial and error process. I tried to use parts that could have been available in the last 80s /first 90s - during the Phase II of the Gray Era and the advent of 9v era. And here it is...it recalls me a "fat" 7727/7730, with a touch of 7810... 8-wide gives some possibility also to work with odd number of studs (boiler is 5 studs wide instead of the classic 4-wide used in standard 12v steamers). I kept the standard cylinders, the ladders, rods, red buffers and magnets, which fit nicely an keep the 12v feeling alive. I used Some SNOT for the doors, using headlight bricks. Everything was already experimented at the time (e.g. the B-model wagon with horizontal sliding doors in 7735 instructions). Right side is quite symmetrical to the left one, apart some details. 12v motor looks nice, now that the body is correctly larger. Weights can sit on top of the motor - but the model could already be sufficiently heavy to have some decent traction and pulling power. I think adding lights won't be a problem nowadays, but for sure at the time (80s/90s) it could have been an additional challenge ! But...there are some issues that must be noted: The buffers overhang is quite...massive - and this SURELY will create problems with 12v switches, since the buffers will collide with the switching electric mechanism. Coupling wagons on R40 curves could be impossible...since this BR80 is longer than any other 12v locomotive or wagon not based on bogies chassis. Weight of a complete train could be excessive for the poor 12v motors. I think it has been a very fun experiment, a real "12v+" MOC...but being realistic - in my opinion it's too limited by the motor, wheels size...and 12v track geometry itself . Maybe, with 3d printed 12v wheels and a PF-based motor it could work on PF flexible track - but it would then loose 90% of its "vintage" appeal. I'd classify it as "Virtual Shelf Queen" ! 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, after seeing the beautiful V60 created by @Asper, I realized that I've never tried to represent it (I started with the V80 and V100). Being the iconic 7760 historically identified a s a V60, I did not pay too much attention to that specific group of locomotives. But it's a nice shunter and has a pretty complex shape, so I wondered if it could be possible to replicate it in 12v-style. The result is pretty similar to the 7760 and to the red little locomotive shown near the car-loader in 7777 book. The front hood starts in 4 wide, then becomes 5-wide to return again to 4-wide. The rear part of the cabin is 5-wide and features low doors (standard train doors were too big). 2x1x2 blue windows are going all around the cabin (no absurdly expensive 3x1x2 windows needed!) I did not mean to make it too complicated, but at least representing the enlarging/restricting body was mandatory to make it different from the 7760. Paint scheme and the headlights were made to elaborate a bit the front and rear parts. Some handrails made with bars could have been nice, but were not existing as parts at the time. I made also the red version with yellow stripes - just to see how it was like. The more I look at it the more I think also the V100 needs some restyling, now! That's all for the moment! Ciao! Davide

Hi there! Over several years since the rise from my dark age I`ve been a silent reader of this thread. Most of you guys already know my stuff from flickr (Simon Jakobi | Flickr). I focus on german engines from epoche III. Lately I added a small part to a great article by Enrico Lussi of at brickmodelrailroader.com (Baureihe 01 and Baureihe 01.10, the pacific’s of the Deutsche Reichsbahn made in LEGO | Brick Model Railroader) and noticed that my english is not in that bad kind of wrotten state as I feared. The first of my latest MOCs I want to share with you is my approach to the german Baureihe 50 - a very common sight on german rails in those days. I focused on the pistons, cabin and boogies of the tender. The engine is equiped with two PF train motors underneath the tender and PF light units. It is controlled via PF IR receiver. The rods were supplied by bricks-on-rails.de. Decals where purchased over at modellbahndecals.de. Currently I´am working on a second version with an alternative concept of motorization. I really would like to power the main axles of the engine by two PF L-motors hidden inside the boiler. I hope you all can see the photos. Let´s give it a try!

DB KLV 53 Hi, this time I want to share a really small vessel with you which gave me countless sleepless nights. P1110480 by Simon Jakobi, auf Flickr To be honest, designing such tiny vehicles is a nightmare compared to the big engines! P1110485 by Simon Jakobi, auf Flickr This is my interpretation of the KLV 53 "Rottenkraftwagen" of the Deutsche Bahn. P1110476 by Simon Jakobi, auf Flickr I learned from the first tests, that when it comes to the constellation of low weight and two axles all wheels have to be powered to avoid hang-ups on switches. DB BR KVL 53 drivetrain Simon Jakobi by Simon Jakobi, auf Flickr That`s why both axles are powered via worm screw by an excentric PF-M-motor beside an "excentric center" axle underneath the loading platform. P1110472 by Simon Jakobi, auf Flickr The motor is controlled via PF-IR-Receiver. The adapters are covered by the chains and the maintainance and construction site stuff. P1110463 by Simon Jakobi, auf Flickr Power supply is an old black 9-V-battery underneath the flat car which is connected to the second output of the IR-receiver... No PF-cables or PF-adapters were harmed. P1110468 by Simon Jakobi, auf Flickr The result is a slow but strong and reliable engine with precise speed controll perfect for low speed action in the "Bahnbetriebswerk" on our LUG-layout. I hope, you like my approach. Bye, Simon!

Hello everyone, and thanks for stopping by! I´d like to show you my MOC of the DB Class 143. The proportions, similar to my class 111, aren´t 100 percent perfect to the prototype, but i´d like to think that it fits well with the official lego city trains. Maybe some of you guys will like it, if not that´s okay too Hope you enjoy the pictures, feel free to comment and critizise!

Two great trains are dueling on 12v gray track: the British Railways HST 125 vs the Deutsche Bahn BR403 "Donald Duck"! Two big countries with high expertise on trains,two different power sources (Diesel vs Electric), same speed (above 200km/h or 125mph). Who will win this Lego contest? None of them, since they both are built on the same Lego platform and shape - I created first the "Donald Duck" in Lufthansa colors and then I modified it a little to recall the HST125. So same power cars ,and same wagons, only with a different paint scheme . I've always focused on standard trains, and this is my first experiment with fast ones. After all , during "gray Era" we've seen a lot of steamers, diesels, electric trains...but only one example of fast train. So here's a shot of the DB403, with an applied sticker on front "window" to simulate double windscreens... ...and one of the "Screaming Valenta" - here the sticker is a bit different, but you can easily tell it is only a bigger one! Both are using parts available in the last years of "Gray Era" (so they could have been made starting from 1987). The HST could be a bit older than the 403 - since it's using the old style blue window in the cabin. I could also recreate a yellow sticker to cover the outer part of the trans-clear headlight, but I preferred to keep it as it is (just imagine the sticker detaching when the glue is old...I HATE that sensation ) Both could have working headlights, the DB403 can use a 12v light brick on top headlight. For the HST125 the problem is how to diffuse light from light brick to transparent slopes. But both trains could also leverage on 9V lights, which were already available at the time. The 9v Battery box fits easily in both bodies. Finally the 7745 has some internal competition!!! Hope you like these two! Ciao! Davide

Hi all, I gave another try to the new 12-wheeler chassis, and this time I could not resist to recreate another iconic locomotive. The real DB E03 is based on a CoCo wheel arrangement, so the 7740 locomotive was more accurate on this aspect. But I'm in the "Blue Era" , so I am a bit limited to the 4,5v/12v motor size and "rigidity". Therefore, my DB E03 is still a 12-wheeler, but in a BoBoBo-like arrangement. Don't tell anyone! This is my first DB E03 - I've never built one in other styles or sizes, apart the 7740. I chosed the first one produced since i liked that silver middle line separating the red and the yellow parts. It can be built also as a DB E103, removing the gray line in the middle of the body, adding a second line of lateral grilles, and changing the pantographs to the one-armed model (it was already used in the late 70s - so it fits the Blue Era). The correct wagons for this one could easily be the Rheingold ones, but in red/yellow color scheme. They should be a bit longer too. In this case, they would be also a lot heavier, I wonder if the 12v motor can pull such heavy things on highly-uneffective wheels lof the time. I hope you like it! Ciao! Davide

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!

Hi all! After the projects, it was time for some real building. I am in "12v phase" so I concentrated on the BR50 I draw during Christmas Holidays: Since there are many expensive parts, I used what I already had at home. I ordered the two front 1x1x2 windows and a pair of big wheels. Here's the final result: It is similar to che project, but it's quite different in some parts: - Front bogie was redesigned completely - while perfectly working from turning radius point of view, its overhang made the locomotive to hit the 12v switch remote control! Now the lower part is turning according to bogie, the buffer turns too. - Chassis is higher, in order to accomodate some details (by the way, the BR50 had small wheels so I needed to increase the space between the wheels and the body. - Flexible Pneumatic tubes instead of black "antennas" to reproduce side pipes (I found this solution more...7777-ish) - Cabin is half stud lower and has a longer roof to cover part of Tender. - Some details are different, and were thought directly "on the run" - Tender is a bit longer, the one I designed was wrongly shaped. Bogies worked fine with the central ladder, but I did not remember the motor has rubber bands on it (and they get stuck on the ladders). - The connection between the thender and the locomotive is using a very very vintage part from the 60s - 12v Motor is now in the rear part of the Tender, since the unpowered bogie was easier to modify in order to accomodate the fixed bar coupling. ...and now some photos: In general, it was built thanks to some incomplete spare sets: a 7715 (doors, two red buffers, boiler parts and some wheels) , a 7810 (two windows, red ladders and black parts) and a 7710 (black parts, some plates...). It was a real fun to build it!!! I hope you like it!!! Ciao! Davide

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 all! I just wrapped up the brick-build of my latest project... a Deutsche Bahn BR 189! It is a predominantly freight-focused locomotive used on international services (notice the multi-system array of four pantographs). I started the build using Stud.io, and purchased all of the required bricks using the Bricklink wishlist integration. Very cool and very easy. The prototype... My "final" render (this design was changed a bit during the build process): Papa und kind (Minitrix version): Front lights: Rear lights: Internals: Lokführer Hans:

I have just completed the modifications to incorporate the suggestions for my 6 wide power functions shunter. Please let me know what you think and I welcome suggestions for how it can be improved. Thank you all for your support on https://ideas.lego.com/projects/82031 I regret we have only 100 supporters now so I don't forsee this getting up as the 50th anniversary of Lego Trains train. Fortunately James Mathis has what I think is an even better idea https://ideas.lego.com/projects/86744 so if you haven't supported this one I can highly recommend his. The biggest change is the ability to now turn the battery box off and on by pressing the front of the forward dome. I have some pictures on Flickr that show how it works. https://www.flickr.c...57649279163680/
