There were only three of the strange 0-8-8-0 Camel backs ever made, and they all went to the Erie Railroad and were used as pusher engines on coal trains.
In this short video we see my MTH Premier Angus as it gets into position to push a train up a hill.
This engine was an uncataloged model from 2004 and is equipped with Proto Sound 2.0 and MTH's DCS command system.
Enjoy!
