This railway was renamed Denver & Salt Lake in 1912.
Adding to the Consolidation stud that had already been assembled (see Locobase 11435), this batch adopted Walschaert outside radial valve gear. This railway was renamed Denver & Salt Lake in 1912.
D & S was a contracting firm that bought this pair of low-drivered Consolidations.
They sold the 23 to the Charleston, Clendennin & Sutton of West Virginia. There followed a string of sales for the 23: CC & S to the Coal & Coke Railroad in May 1903 as their #9. The C & C operated the engine for more than 15 years before selling the 9 to Middle Creek Railroad in 1919, where it was renumbered 4.
The 24 was sold to the McDonald & Onderdonk, New York City contractors. Some time later, M & O sold the engine to the locomotive rebuilder/reseller Birmingham Rail & Locomotive. BR & L rebuilt the 24 with 20" cylinders and sold the locomotive to the Davidson Ingram Lumber Company of Houston, Tex. The DILC sold the engine to Benford Lumber inVirginia and that company later sold it to the Mardez Lumber.
