Selander Posted February 22, 2012 (edited) This build started as a concept to see if it was possible to integrate PF XL-motors (5 studs diameter) within a 6-wide body. I figured out some alternatives: 1) SNOT:ed panels 1x2x3 between technic bricks 1x1. 2) Train doors 1x4x5. 3) SNOT:ed tiles 1x8 placed vertically. I continued with the first alternative, and from the new Cars set 9486 I found panels 1x2x3 in Green which inspired to make a sleak locomotive in typical German or Swiss style. To show off the two XL-motors I put trans-black panels 1x2x3 on top. By building a 6 x 34studs long locomotive, I squeezed in 2 XL-motors, a PF battery box, on e IR receiver, and a pair of LED lights in each end. In each pair, one Led goes to the upper round single light and the second enlightens a green light prism (from 7897). Front end has clear /yellow lights, and rear has red lights. Bogies are 3axle designs, with a floating mid-axle (Inspiration comes from Railbricks issue 6 by Scott Wardlaw)which allows you to use standard PF train wheels without any o-ring modification. Each bogie is powered by a vertical XL motor to a 20T gear. Still the loco is quite slow…. Feel free to comment. Edited February 23, 2012 by Selander Share this post Link to post Share on other sites

JopieK Posted February 22, 2012 Vry nice indeed, looks a bit like 7740!!! Share this post Link to post Share on other sites
roamingstop Posted February 22, 2012 Im curious to how you finished off the green panels - is this the 'illegal' technique of using a 1x1 technic brick? Certainly a very good design; I had struggled to find a decent set of panels to do something similar for a model once. Nice solution as always! Share this post Link to post Share on other sites
adrian_dixon Posted February 22, 2012 Very good. Would b interesting to see how it went if you used cales geared up truck design. Share this post Link to post Share on other sites

Selander Posted February 23, 2012 Very good. Would b interesting to see how it went if you used cales geared up truck design. Thanks Adrian, bogies are actually already geared-up by using a 20T gear to drive all 12T gears. Was it that you refer to when mentioning 'Cale' .. ? Still, a XL-motor spins slowly.....
