When the passenger trains became faster and longer, and the Pacifics' were having difficulties maintaining the schedules, the UP decided on the 4-8-2 "Mountain" type to take up the load. They were built with high drivers and plenty of power and served the UP well until 1956.

BLI's model will be patterned after the rebuilt version with a disc main driver, Walschaerts valve gear and "Sweeney" stack, and will use a 12,000 gallon Semi-Vanderbilt tender. We will also offer our Mountains in their black attire as well as in the two-tone gray and white passenger scheme.
