Paperinik77pk posted a topic in LEGO Train TechHi 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
