Berkshire Productions operated originally from 1984 to 1992 with a number of professionally filmed and edited programs by Grant Geist. This footage showcased a number of steam locomotives across the United States on the mainline and more. There are 37 programs currently available on 32 DVDs and Blu-Rays. This represents the entire available Berkshire catalog.

Special thanks to Rich Melvin, Joseph Ayer, and Grace McKay for their help in this project.
