4-8-2 Heavy Mountain
The USRA Heavy Mountain “T” Class steam locomotive was a USRA standard class designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. Southern Railway operated 63 of these units. Most of these were built around 1919.
There are two Buchman 4-8-2 Mountain units on the A&BR, one hauls a short log train and the other is damaged and currently resides under the old coaling tower on the approach to Altamont Yard.
