Bユニット
The Haysi Railroad probably was best known for its unorthodox motive power, which included an EMD F7 B unit that was built in 1949 as Clinchfield Railroad F3B #852, and later upgraded to an F7B. The Haysi Railroad had acquired the B-unit, renumbered it to #1, and equipped it with radio controls and a makeshift cab in 1972.
