Thought I'd take up Tingoat's idea of a modern day version of the Denver & Rio Grande Western's "Galloping Goose". For those not familiar, the D&RGW made a 3 foot gauge light service freight and passenger vehicle out of a box car and a Pierce Arrow touring car. My modern version is HOn30 using a 25' foot trailer and an older Chevy Suburban. This all is mounted on an N scale Bachmann U-boat mechanism. Here it is outside of the shop, awaiting it's Suburban body and drive train. I'm already pleased with the effect so far. The original Goose boxcar ran on two four-wheel trucks with the automobile powerplant resting on its own undercarraige. This one is following that basic design fairly closely. At just under 10' tall at the railheads, it is dwarfed by my B&O Docksider.
