Working with them were the "800-class" high-speed passenger locomotives, as well as hundreds of older class steam engines. The locomotives of the Mt. Washington Cog Railroad are examples of this type. 0-4-0: Four-coupled: 0-4-2T: 0-4-4T: Forney four-coupled: 0-4-4-0: 0-4-6T: Forney four-coupled: 0-6-0: Six-coupled: 0-6-2T: Several examples were built by Baldwin (25896,25953) for the Uintah Railroad. 0-6-2: 0-6-4T: Forney six-coupled: 0-6-6T: Forney six-coupled: 0-6-6-0: 1904,Baltimore & Ohio.
