The H-4 class includes a total of 16 Consolidations built by Baldwin, divided into ten of the actual class H-4 from 1901 and six H-4a of 1903. Some sources state that like the H-4b, these were originally built for the West Virginia Central & Pittsburgh and only came to Western Maryland in 1905.

While most of the locomotives were retired between 1927 and 1931, the 401 and 409 came to the Chesapeake Beach Railway. The 409 rejoined the Western Maryland in 1935. Four units were sold to the Vang Construction Company. The 406 and 416 survived to 1941 and 1946, respectively.

Western Maryland No. 6 (Shay C-150-3)
United States | 1945 | only one produced
In May 1950 in Knobmount, West Virginia

collection Taylor Rush

The heaviest Shays belonged to class C and had three two-axle bogies with a service weight of 160 short tons. Likewise, the class D with four bogies up to 150 short tons was offered, which could score with slightly lower power figures with larger reserves and a higher adhesive weight. A common model with three bogies in the 150 ton weight class is presented here. In terms of the number of cylinders, it did not differ from the smallest B-class models, but the cylinders were significantly larger with a diameter of 17 inches and a piston stroke of 18 inches.

The Western Maryland Railway already had one C-70-3 and one D-150-4 type and procured another C-150-3 in 1945. The special thing about this locomotive is that it was the last of about 2,770 Shays built. After the Western Maryland introduced diesel locomotives on main lines beginning in 1949, the number 6 was retired in September 1950 after only five years of service. In 1953 it came to the Baltimore & Ohio Transportation Museum and from there it has been on loan to the state of West Virginia since 1980 for use on the Cass Scenic Railroad. It is considered the largest operational Shay today.
