The American Locomotive Company (ALCO) introduced the PA1
locomotive in 1946 to offer direct competition with EMD's successful
"E" Series Passenger diesels. The first PA1 celebrated Alco's 75,000th
loco to roll out of the erecting shop. This attractive 2000HP loco was their
high-speed passenger diesel. Having more horsepower than their leading
competitor, Alco felt that they had a fleet-ready competitive product.
With orders from 16 railroads, Alco was able
to produce a total of 247 "PA" units and 47 "PB" units until
production ceased in May 1953. The PA locomotives remained in U.S. service until
1978 and were a very important part of the time period known as the
"Transition Era" where steam was replaced with the diesel.
PA1's were stylish, sleek, powerful and were
very well-suited for America's passenger and fast freight trains.
Additionally, their 65' 8" bodies became excellent billboard advertising
for the railroads that they served with pride.
