An American Crocodile?

In 2004, MTH released another in their series of die-cast models of Pennsylvania RR electric locomotives.  This was the L5, a prehistoric-appearing steeplecab locomotive that was the last of their experimental jackshaft electrics.  The jackshafts were a breed of locomotive that conbined electric motors with steam locomotive side rods to move the drivers.  The prototype was first built in 1924, and was intended for both passenger and freight operations.  In this True HD 1080p video, I've coupled the L5 to a short Pennsy freight train.  In the final segment, you can see it uncouple from its train and head back to its track in the locomotive ready yard, all under DCS remote control.
