I thought I would post this for those who might be interested, I ran across these on flea bay where they were listed as 1/43; they are actually 1/48, but they are O-scale so about what we are used to and Pretty close.
Great thing is they look really good and a really inexpensive and would make it quick and easy to add some drama to your circuit.

I am entertaining getting a few myself when the time comes, but until then . . .
