KINGSTON, N.Y. — The Catskill Mountain Railroad has converted its locomotives to run on 100% biodiesel fuel and says it is the first heritage railroad in the country to do so, the railroad has announced.

The railroad operates with a pair of Alco locomotives. RS1 No. 401 was built in March 1950 for the Illinois Terminal Railroad and later property of the Gulf, Mobile & Ohio, Illinois Central Gulf, and Green Mountain Railway. S1 No. 407 was built in 1946 for the Long Island Rail Road, moved to the Staten Island Railway in 1977, and was acquired by the Catskill Mountain Railroad from a broker in 2010.

Biodiesel fuel reduces carbon dioxide emissions by 74%, carbon monoxide by almost 50%, and hydrocarbon emissions by almost 70%, according to the U.S. Department of Energy. The railroad is being supplied by local firm NetZero Biofuels.
