Indexed by Moderator After a long time I'd like to introduce my new train MOC, which one is actually my first 6-wide train, the narrow-gauge Stadler GTW. Fig.1: The whole train on brick-built train track. The second meeting in 2012 of hungarian LEGO users group (MALUG) was held last weekend in Budapest. Before this event on of our LUG members called others to build narrow gauge vechiles for the meeting. After thinking about my possibilities and favourited vechiles I started to build the first popular vechile of Stadler, the GTW. The coloring of this train is not autenthic, there are no OBB/SBB colored GTWs in narrow gauge, but I had only red and white bricks to use. The real challenge was to build the PF-system into the train and make it able to run on narrow-gauge train track (the curved track pieces from Indiana Jones sets in dark bluish gray and from Space sets in black). The LUG member called others to build narrow-gauge vechiles set up a test-track for all trains, built from this curved track pieces, including two S-turns. That was the test-track (with the little green train): http://www.brickshel...11/dsc_1882.jpg Firstly I've realized, that I've had to build one and half windows less to the modell then the original train. The radius of these curve is 27 stud, and my train actual length is 90 studs. The middle-section contains two PF M-motors, both of them are driving one axle via 12 tooth-gear wheels. One of the low-floor sections contains the battery box and the IR-reciever. The train has two yellow front lights on each end, PF leds' cables are hidden in the roof. Fig.2: Driven axles and coupling solution for the train. Left side coupled, right disconnected. The coupling enables about 75° turnout and looks like closed until 30° turnout. Fig.3: Turnout. However I did not have test track for the meeting, the train succeded to run on the test track. The most 'engineering' success for me is the coupling solution. Using SNOT slopes by the coupling looks really great, they are avaliable in lot of colors, and you don't need rubber. This method will work for trains with Jacobs-boogies, too, the only difference is, that the middle section is narrower. The front part of the train is built of prepared modules, it can be repared, changed without getting of the train from the rails.
