Well, that's not what the original post was asking. He was asking about O scale representations of meter and/or broad gauge...
If there's a prototype, then someone somewhere has modeled it.
Regular O scale is actually quite close to the broad gauge that PA trolleys used and those in New Orleans, couple of inches.
