Kennecott Copper Corp. ALCO RSD-4 Diesel Electric Locomotive KCC 201

Locomotive #201 is a model RSD-4 constructed by the American Locomotive Company (ALCO) in 1951. This road locomotive has 1,600 horsepower, is geared for a top speed of 60 miles per hour, and has a total weight of 286,000 pounds.  It is fully operational and often pulls excursion trains on the Museum's Snoqualmie Valley Railroad. 

The 201 is a diesel-electric locomotive: a diesel engine turns an electric generator and electric motors turn each axle.  It has an air compressor to supply air for the air brake system and seating for two crew members.

The Alco RSD-4 was a short-lived production model and the 201 is the last surviving unit.  The prime mover is a 12 cylinder ALCO 244 four stroke diesel.  Notable in this design is the dry engine block.  Coolant is plumbed to each cylinder while the engine block remains dry.

When purchased new by Kennecott, the 201 was used in the company's Nevada and Utah operations to pull trains of ore to smelters.  The 201 is very similar to locomotives used by the Northern Pacific Railway, Great Northern Railway, and the Spokane, Portland and Seattle Railway throughout the Northwest.

The #201 was donated to the Northwest Railway Museum in 1984.

201Br35201 effortlessly pulls a passenger train across Bridge 35.  

201 has six axles.  When compared to the Museum's locomotive 1, this unit has about 1/3 less axle loading, which is easier on the track.

Special Update

ALL TRAIN PASSENGERS AND CREW MUST WEAR MASKS

Why do we still require masks? Transportation Security Adminsitration ("TSA") regulations currently require all railways, airlines and buses to have persons masked through January 2022. Though social distancing regulations are loosening in much of the region, the Snoqualmie Valley Railroad falls under the jurisdiction of the Federal Railway Administration and TSA. We ask that all visitors over the age of 2 and require for those over the age of 5 to wear a mask that covers both nose and mouth while visiting. By order of King County, proof of vaccination will be required beginning October 25 for all visitors aged 12 and older. The vaccine requirement is a legal mandate imposed by King County. The Museum is required to enforce the law as a condition of remaining open to the public. The Museum has already lost $1.4 million from closures and capacity reductions, further closures would be absolutely disasterous to the Museum. For more information about our social distancing restrictions please visit our Social Distancing Updates page.
