CSX Media Relations Manager Laura Phelps tells Trains News Wire that the low emission locomotives will be assigned to Atlanta; Chicago; Camden, N.J.; and New York.
“The low emission locomotives are ideal for moving and sorting freight in our yards, providing a more environmentally friendly way to build trains around the clock and efficiently serve customers,” Phelps says.
The new SD40E3s are a separate program from the railroad’s own SD40-3 rebuild program. Wabtec’s MotivePower Inc. in Idaho has been rebuilding retired SD40-2s into SD40-3s for several years. The SD40-3s are in the 4000 numbering series.
When asked if the SD40-3s will continue being rebuilt, Phelps says that the Eco units “are not intended to replace the SD40-3 units” and that CSX is still “evaluating how the [SD40-3] units might be used to fulfill our future needs.”
The first batch of rebuilt SD40E3 locomotives were recently spotted at the railroad’s Tilford Yard in Atlanta.
