Could it be done?

That's not a bad idea.

I'll point a colleague from the Club at it since he wants to make the horse-drawn narrow-gauge tramway from the gunpowder works to Haverthwaite work, by hiding a z-gauge loco chassis under a wagon.

He still hasn't come clean about how he plans to get Dobbin to the other end of the wagon to take it back, though.

Easy, shed at each end and 2 wagon/horse combinations

Bit tricky, there ain't room - the narrow gauge tramway is between two standard gauge sidings.
