I like the late-1930s car from 2015 San Diego Comic Con set 'Action Comics 1 - Superman', but didn't particularly care for the garish colors of green and yellow - or the insane price!
So I used the instructions and built my own normal version in dark blue, then this black one with XS Big Ben Bricks train wheels instead of rubber tires as a railroad inspection vehicle. This rail mobile has a number of changes from the set, but it still seats one figure at the wheel. Speaking of which: the person in the picture is a division superintendent, and he is wearing green in tribute to the original colors of the SDCC set that inspired this MOC.
The rear of the rail mobile. (apologies for the dust - I just built this two days ago!)

Thoughts?
