It didn't take long for these engines to be pulled from premier passenger service due to their reliability issues.  About half the pictures I have of BP20s show either an A-unit by itself (pulling 3-4 cars in commuter service) or in an AB consist pulling express cars.

The nose of the engine in the first and later posts is not of a passenger shark.  I agree it most likely came off a freight shark.  However, who ever built the engine did a good job.
