What is alco rs-2?

The ALCO RS-2 was a diesel-electric locomotive built by the American Locomotive Company (ALCO) between 1946 and 1950. It was an upgraded version of the RS-1, with increased horsepower and a longer body to accommodate larger fuel tanks. The RS-2 was designed specifically for road-switching duties, meaning it was built to switch trains from one track to another on a main line while not being confined to a specific yard or location.

The locomotive was powered by an ALCO 244 V12 diesel engine and had a maximum speed of 65 miles per hour. It was typically used in freight services, and several railroad companies in the United States, Canada, and Mexico owned and operated the RS-2.

Overall, the ALCO RS-2 was considered a reliable and versatile locomotive, with many units remaining in service for several decades. However, as technology advanced and more efficient locomotives were developed, the RS-2 was eventually phased out of service. Some units were preserved in museums or sold to smaller railroad companies.
