Suzy-Q RS1 in Edgwater NJ

[Erie Lackawanna]

On January 8, 1980, I found two NYSW RS1s switching Edgewater Yard.  Does anyone know what the symbol of this train would have been?  

The only thing in these pictures still there is the blue building behind the train.

Here's the entire train.

Any corrections are appreciated.  I hope you enjoy.
