Rapido HO Scale ALCo PA & PB Locomotives

The ALCo PA series locomotives are considered by many to be the most attractive diesel locomotives ever produced. The PA locomotives were built by a partnership of American Locomotive Company and General Electric between 1946 and 1953. They offered two models, the PA-1 initially followed by the PA-2. Both were powered by ALCo’s 16-cylinder 244 diesel engine generating 2,000 HP in the PA-1 and 2,250 in the PA-2.
