Well finally you guys can see a couple of our Plymouths that came from the undergound clay mine for the Stone Creek Brick Co. in Ohio.
The orange locomotive is:
Plymouth
Model: DDT
Gauge 36"
Weight 8 ton
This unit was originally built for the Dupont factory with a cab in Carneys Point, NJ.
Plymouth removed the cab & changed the fuel system so it can operate underground.
The yellow locomotive is:
Plymouth
Model: HMD
Gauge 36"
Weight 8 ton
Built for Stone Creek as a Hydrostatic drive model
The frame is actually dragging on the rail head
