  1. 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
  2. Hi all, during a pleasant discussion in this thread... ...a very interesting question was raised by @SDLgo9 member: The 7777 idea book pages mentioned here are those three pages showing the blue matter (!) unloading station and the famous auto-unloading wagons. These wagons are pulled by an obscure locomotive, which is never fully depicted. In fact - the front view is missing, and there's no clear view of the boiler. I've NEVER taken care of it, nor analyzed it too much. It really seems a 7730-based locomotive, but simplified in some details. There's a strange combination of "simple look" and now overpriced rare parts. So maybe it's simple - but it is a wanted effect? Analyzing the whole scenery depicted in the book - it's not a place for a fancy locomotive. There's work to do - wagons are fully loaded and heavy, so that unloading station surely needs a workhorse. And these workhorse is powerful, maybe not so good looking, but simple and solid, ready for its everyday duty. Here's a rear view, similar to the one in the Idea Book: It's a long locomotive and it's not using the classic train base (like 7810). It's pretty boxy and looks heavy. I had to take the scans from Brickfactory and to modify the photos to see a bit better. But which parts were used of the body is pretty unknown to me. So, we have the 2x2x1 black windows on the rear part - being a 7730 derivate - there are also doors, and at this point, the 1x2x1 small black windows. But it seems (to me) that these are not facing towards the front, and instead are used as small side windows. Side reservoirs are big, so fitting the two weight bricks was not a problem. The smoke stack is visible and there's not so much to say - but the boiler...is not completely visible. I added a square steam dome just for completeness. There's an headlight on top of boiler, and it seems there are also two headlights on the "nose". They are not fully visible, for this reason I think these are not placed on the corners of the chassis. Let's try: Simple and straight - the boiler is not round, but goes down to the chassis, same "steering wheel" as in the 7730. Headlights are a bit more inwards. All in all it's a simplified 7730 nose. Then, a more "Narrow Gauge" look - always with 7730 parts: There could be more styles, just removing the front steering wheel part and playing with slope parts. Suggestions are welcome!!! Davide
  3. 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
  4. Hello In the iconic idea book 7777 there's one diorama with a circus. The train that pairs with it happens to have a battery box car with a clown sticker on it. However, there are no such battery boxes on bricklink from what I can find. I'm assuming the sticker comes from a different set, but I don't know how to find that. Could anyone happen to know what set features the sticker? Edit: found out it's from the 6000 idea book
  5. I've built up a layout to drive around my 3 meters long Octan train. The locomotive is based on the vintage 7755 shunter locomotive. In the 80's 7777 train idea book there's on some page an oil refinery. I've built that one in Octan colours! I've added a few lights to the loc: when the loc is driving forward, the yellow light is lit, when it drives backward, the red light is lit: And ofcourse, I've made a video!
