Cotton Belt GP40
delivered as GP40's 7600-7607 in 1966
8 units delivered
If your into nitpicky type details, I have a breakdown of the GP40 family and their relevant features. Click here if your brave.
The Cotton Belt actually ordered another lot of GP35's #782 - 789 in mid 1965 for delivery in early 1966. But instead, received the new model EMD GP40's.
Six F7A's and two F7B's were used as trade-ins, the GP40's being delivered between January and March 1966, numbered 7600 - 7607 and classed EF430C-1, as well these units came with snowplows instead of footboards.
The Cotton Belt GP40's weren't a total success, perhaps being the first of a new model, and 750hp per axle being a bit slippery for the usual heavy SP train and SP's track profiles, these units often found themselves being placed in storage.
The GP40's were used system-wide on run-through trains, as evidenced by the photos above, also they spent a lot of time on the Penn Central, and some were leased to the Rio Grande.
In 1982 these units were rebuilt to GP40-2 standards, modified to act as slug mothers and reclassed as SSW GP40R's
