Hi,
i just saw the 50 years of track set - a neat thing, but probably the best item of it is the 4 wide Metroliner.
Therefore i did wonder if i could do the Horizon Express in the same scale and perhaps motorize it.
So i also started the Metroliner first, thought of ways of making a super small boogie still with functionality for a motor to attach to. ATM its rubberbands around bushes for transaction, yet im very unsure if this were to work in a real build if the boogie turns.
I used gears as wheels for the motor unit (if you look close into the pic).
If any of you have motorized a 4 wide train without using standard sized train wheels, id be thrilled to hear/see about it.
