Below are a few photos of my GP7 depicting an ex-South Shore unit that was returned to the Chessie System in 1981.

Below the #5778 shows off its original South Shore numberboards, which it wore well into the mid 1980s, despite carrying the road #5778 on the side.

Below #5778 is seen heading away from the camera.  The painted over South Shore logo is quite evident at this angle.
