After the Fitchburg and its component lines (the Cheshire in Keene) were incorporated into the B & M in 1900, the Keene Shops maintained B & M work equipment. Keene was closed in the 1930s and work moved elsewhere; probably most went to Concord, NH.
Thanks, that was my understanding. I became confused by lazy journalism from the Keene Sentinel in a recent article on the Cheshire Rail Trail which mentioned that the shops "closed 50 years ago."
