[MOC] Chilean "Gondola Carril T-1024" in 1:22.5 scale
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, today I'd like to show you something I'm after since a few months. During the first days of lockdown I saw a documentary on Chile and its people, towns, traditions and lifestyle. One of the main points of the documentary was focusing on the railway running from Los Andes to Rio Blanco valley , a spectacular run between mountains, aside the Rio Blanco river. Originally it connected Chile to Argentina. And this "thing" was presented as the main attraction of the current line - its name is "Gondola Carril T-1024". I sincerely do not know why it is called "T-1024" . The "Gondola Carril" is a railmotor, based on an American built bus, the Yellow Coach Z-26. This time I understood that the letter Z is identifying the chassis type and 26 the number of passengers it could carry . The bus was normally used in Los Andes town, until it was converted into this very nice railcar. Originally used as a cheap inspection vehicle, It is now fully restored and used for touristic travels. And I can say it is an experience I would like to do once in my life. The "Ferrocarril Transandino de Chile" is a narrow gauge (metric) railway, therefore I based the whole project on 1:22.5 scale (good for running in the garden!). It is designed to run on G-Scale track (45mm), but with some modifications it could easily be converted to run also on standard Lego gauge (on large curves, since it is quite long). Since there are no specific technical specifications for the Gondola, I searched for the ones of the Z26 Bus - and tried to adapt the design according to the pictures and videos of the real railcar. The original motor used by Yellow Coaches Bus was replaced by a more modern Cummins Diesel, as nicely "declared" above the radiator. Despite the original railcar is based on a chassis, this one is basically a unibody build with some underside reinforcing (let's say - like the Jeep Cherokee XJ). It's quite light, so a medium motor is sufficient to move it. In the design, I used a PuP motor, placed in the front, under the hood. Then a pair of gears in cascade, cardanic joints and a transmission axle bring the power to the rear wheels. The "gears" I mentioned can be changed easily to have a lower or higher gear ratio, as needed. This railcar not meant to pull anything, so a lower gear ratio could save some batteries. Battery box is placed in the rear part, immediately beyond the rear axle. The small red axle you can see near the T-1024 sticker is used to turn the PuP battery/receiver on and off. The next picture shows the powertrain - it's taken from an alternative blue version of the railcar I prepared , with some freelance solutions which make it more "generic". I hope you like this one, and (more important) take a look to the original one, because it's really nice piece of history. https://www.ferrocarril-trasandino.com.ar/historia/ Ciao! Davide -
Hi all, after a quite long absence from the forum, I'd lilke to show you this small MOC I just prepared. It should have been a model for the Octrainber, but since I've no time to prepare the whole diorama, I'll show you only the little railcar. The Egger-Bahn is a model line created in the 60s, based mainly on fictional freelance rolling stock (even if some models were inspired by real prototypes). These models were in 1:87 scale, running on H0e track - therefore simulating a narrow gauge system. One of the main models was the articulated steam railcar you can see in this picture taken from internet. The lillte railcar is articulated and composed by a steam motor and an half-passenger wagon. It is a very nice model and I've always liked it! Since I'm working a lot on big scales, I wanted to do something different, so I got back to 6-wide on 4-wide track: It's super-deformed as my other small locomotives I made , and it's based on the 9V red MicroMotor. It can run on black Lego narrow-gauge track and on LEMAX Christmas Train track - which is perfect for small Lego models (and features straights and larger curves). Here below you can see the different components, like the MicroMotor, the rear bogie, and body parts (motor and trailer). And here's a detail of the motor and passenger trailer. As you can see, the 9v MicroMotor is mounted upside-down, and moves the rear wheels of the steam motor. The power comes from a 9v battery box, but I succeded to run the Micromotor on small 12v batteries. Some home made electronics may save space! The batteries should be placed near the trailer link, therefore their weight - insisting on the only driven axle - can improve traction. I hope you like it! Ciao! Davide

I thought I'd show off a model here, thought it'd be a nice way to introduce myself too. I'm a Lego fan who loves Legos, Doctor Who, and steampunk. I've been building models in Lego Digital Designer for sometime now, and thought I'd start off with a steampunk-styled railmotor. I've taken some inspiration from a GWR Railmotor, a tramway car, etc, combined them into a steampunk-esque fashion, and combined them together into a steampunk-like railmotor. First up, here's a picture of the front bogey, which powers the railmotor. I'm not very experienced with making complicated valve gear, so I decided to go with a basic 0-4-0 wheel configuration and just some basic siderods. Here, we get a nice look at the inside of the undercarriage, showing the inside motion valve gear which powers the wheelset. I think it looks rather nice myself. Next, we have the boiler inside of the railmotor, located in the cab where the crew work. The boiler design is based off of a steampunk-inspired moc in the link here: http://gwenix.org/~adams/lego/balloon/index.html If copying or getting inspiration from other MOCs is against the forums rules, then I apologize, I'll have another look at the rules. Here is the right side of the boiler, which slightly differs from it's original prototype, having additional gears on the side as well as a larger firebox door. I originally wasn't planning on adding the gears, however I decided to add them anyways, just to give the design a more steampunk-inspired feel to it. Feel free to leave any feedback down below as well as any suggestions. I am also glad to accept any assistance with any of my models.
