LTK-designed railcarOld locomotives get new lease on life. 

Connecticut DOT operates commuter rail service within the state. Fourteen locomotives serving the Shore Line East (SLE) from New Haven to New London required overhaul to extend their service lives. There were two kinds of locomotives: eight P40s from General Electric originally built in 1992 and six GP40s from Electro-Motive Diesel originally built in 1971 and remanufactured in 1996.

LTK has managed the work on both types. The P40s are getting a complete overhaul that will rebuild major systems, including the prime mover, main alternator, traction motors, automatic train control, and friction brake. The six GP-40 units will receive a top deck overhaul. This work will consist of replacement of major engine parts, with inspection and replacement of other components as needed. LTK has assisted with all phases of the project from specification development and engineering support during manufacturing through follow-on engineering support and warranty and project close-out.

These overhauls will extend the life of the P40s by 12 years and the GP40s by six years.
