Allegheny Steam Locomotive, 1941

Summary

The Chesapeake & Ohio Railway's massive Allegheny, introduced in 1941, represents the peak of steam railroad technology. Among the largest and most powerful steam locomotives ever built, it weighed 1.2 million pounds with its tender and could generate 7,500 horsepower. Just 11 years later, C&O began pulling these giants from service. Diesel-electric locomotives proved more flexible and less expensive.
