What is chesapeake and ohio m1?

The Chesapeake and Ohio M1, also known as the C&O M1, was a steam locomotive that was built by the Lima Locomotive Works in 1947 for the Chesapeake and Ohio Railway. It was a massive machine, weighing in at 551,000 pounds and measuring 120 feet long. The C&O M1 was designed for both freight and passenger service and was one of the largest steam locomotives ever built.

The C&O M1 was powered by a 4-8-4 wheel arrangement, which means it had four leading wheels, eight driving wheels, and four trailing wheels. It had a top speed of 70 miles per hour and could haul up to 160 cars. The locomotive was also equipped with a Worthington feedwater heater and a Franklin Type A anti-deadhead device, which helped improve efficiency and performance.

The C&O M1 was used primarily on the Chesapeake and Ohio Railway's mainline between Newport News, Virginia, and Cincinnati, Ohio. It was retired from service in 1956, after just nine years of operation, due to the increasing popularity of diesel locomotives. Today, the C&O M1 is considered a rare and valuable piece of railroad history, and a few examples can be found on display in railroad museums and private collections.
