Bachmann 2773 or 62945 trolleys

[skillet]

what are the dimensions in inches for ho gauge trolleys. I am trying to make a setup with 1/64 vehicles and want to see if this is too small "looking"

HO scale is 1:87th while O scale is 1:48th, the trolleys you listed are 1:87th which would be too small. O scale would be too large.
What you need is S scale, which is also 1:64th scale, I think American Flyer made a trolley at some point in the scale you are looking for.

Unless you're into scratch building, the closest thing you're probably going to find would be an On30 trolley running on HO track. Technically On30 equipment is 1:48 O-scale, but the trolleys are small enough to fit in with 1/64 S-scale.

When i am not sure about size i always back calculate what it would be in the real world.
