Rotary Coal Dumper


The rotary car dumpers have been around for decades, dating to back to at least the 1950's if not earlier.

So if you are modeling the transition era on your layout, a rotary coal dumper is perfect for that time era

all the way up to present time. One nice feature is our coal dumper can be installed into your layout top without

 having to have it raised about the layout and use trestle, or if you prefer that look you can  install it into

 a hill and use trestles leading up to and away from it. It's your choice.
