Bill Christopher caught RS-20 #305 at the Norwood Yard office on an overcast April day in 1976.
The GB&W's four RS-20s started life as Alco RS-3s built in the 1950s. They were rebuilt in the early 1970s with new 2000
horsepower V-12 251C engines from the Alco Engines division of White Industrial Power. A the same time the short hood was lowered
and made the front of the engine, as evidenced by the white "F" near the steps.
The RS-20s were mainly used in the yards at Green Bay and Wisconsin Rapids, and usually only ventured out on the mainline when traveling to and from the Norwood Shops for monthly service.
The freight / yard / dispatcher office was located at 503 Twelfth Avenue in Green Bay, right where the westbound yard throat crossed the street. It was a great place for train watching because it was easily accessible and Norwood Yard was usually switched from this end.
