Trains on this day in the past:

[TMo]

12/3/1978. Rochester, Pa. 
Charlie

A rare bird running lead dog on that consist, Charlie.  SDP45 - all of those came from the Erie Lackawanna.  The telltale extra tail end on the long hood is an easy spotting feature.  I don't know if anyone ever bothered to model those in HO, but it would be an interesting project...
