GP40-3 (Wabtec Cab Rebuild)
The true four axle workhorse for the Florida & Gulf Coast Railroad (FGC) was the GP40-2 model. These units were purchased from various sources going back to the original Alabama, Florida & Gulf Railroad (AFG) and were joined by FGC units left by MDRail Transportation after they sold the FGC to Florida & Gulf Industries (FGI). Many of the AFG units retained their L&N inspired paint well into the FGI era and were assigned to road switching and local train service and some branch lines on the combined system. These units launched the Hurricane Intermodal Service in 2018, but were all but replaced as FGI added purpose built GP60, GP39M, GP39MB, GP49 and later SD40-2W and SD40-2F units to the roster to increase efficiency and growth in the business.
As units were sidelined by derailments or severe failures, FGI contracted Stephens Railcar to begin rebuilding the ailing units into remanufactured new GP40-3 units similar to the ongoing SD40-3 Recapitalization Program . The success of the SD40-3 Recapitalization Program prompted FGI to extend the program to GP units. Stephens Railcar added these units to the original scope of the SD40-3 Recapitalization Program and specifications were developed to fully modernize the units. Remanufacturing consisted of each candidate being stripped to the frame and all components restored or replaced to OEM specifications. The cab and main electrical cabinet were replaced with a WABTEC aftermarket skid which included under floor HVAC equipment, modernized and collision protection upgrades and microprocessor controls. The primemover was replaced with a 710 engine and compatible alternator with new traction motors and free flow blower system. All rotary equipment was either rebuilt or replaced following OEM specifications. Completed units were sandblasted and painted in the current FGI Sunburst corporate colors. In addition, PTC was added to allow these units to lead on interchange partner mainlines using PTC control.
The GP40-3 remanufacturing began in 2023 at a rate of 2 units per year. By 2025, five units were completed. Two additional units were sent to Stephens Railcar in early 2025 and were being converted, with three units being produced by the end of the year. These units were assigned in the same pools as the SD40-3 units, mainly due to their PTC capability.
