Wow, I didn't know that CSOR had switchers. Everything I've seen has been Dash 8s
Originally CSO Started with Ex Conrail B23-7's then they had a High Nose B23-7 and some B30-7's and a slug from the ISRR. Now they have 6 B40-8's, 1 SW1500 , and 2 Ex UP CEFX SD40-2's. The CSOR Switcher usually spends most of its time on the NECR in Palmer, MA and in return the CSOR has the NECR GP38 #3869 which is the only High Hood Railamerica painted unit on the NECR roster. I plan to have the entire CSO roster eventually as I am getting custom decals made for the Current CSOR units, switcher, and caboose.
