Here are some more narrow-gauge freight cars, again very-narrow-gauge, although again the exact gauge is now something that I know.

I'm not aware of what mine these mining carts were used in, but they're clearly narrow-gauge, possibly narrower than the other narrow-gauge exhibits at the museum. I wouldn't mind getting some information on the gauges of the display tracks at the museum, so I'm going to log onto the internet as soon as possible and find out.
