Below WM #5961 pushes a Chessie WM insulated boxcar into a siding.  GP9s like this one were seen system wide performing these sorts of local moves.  Notice the unique bell positioned on the nose, clearly showing off this units former C&O heritage.  Although this scene has a WM locomotive and a WM boxcar, it could be anywhere on the Chessie System, as this equipment freely roamed the entire system.

Below #5961 leads two insulated boxcars down the line on a local switch job.  That first car is in the original B&O insulated boxcar paint job while the second one has gotten a new coat of Chessie paint.

Below is a typical location for a GP9 in a main line consist.  GP9s were old by the Chessie Era, so were rarely on the point of any consist.  Engineers prefer creature comforts, like sitting in the newest locomotive available.  If GP7s or GP9s were in a mainline consist at all, they were in the middle 90%+ of the time.

Below is another shot of the same consist.  The lead unit today is a GP38 in its original B&O paint job.  The trailing unit is a Chessie painted GP40.  Locomotive consists of three locomotives in the Chessie era almost always looked like this.  One or two of the locomotives would be painted Chessie and one or two painted in their predecessor paint jobs.  The two end units faced out, while the middle unit faced either direction.  The oldest unit was almost always in the middle.
