The Niles Canyon Railway operates on the alignment of the original transcontinental railroad. However, this Lerro Productions charter was focused on the logging industry. Clover Valley Lumber Company No.4 was based in Loyalton, California. "Skookum" No.7 is an interloper having spent most of its career on logging railroads in Oregon and Washington. Both are examples of Anatole Mallet's design for articulated steam locomotives and both were built by the Baldwin Locomotive Works of Philadelphia.
