Engineer's workout
Polarity and direction of travel on the Baldwin-Westinghouse locomotives are determined by which trolley pole is raised and contacting the catenary. Each time a reverse move is made the operator must leave the cab, manually lower one pole and raise the other. It would seem to be a major inconvenience, but the Iowa Traction employees are quite adept at making the changeover very quickly during switching moves.
