The $162-million Grand Concourse project rehabilitated the signal and communications systems for the NYCT’s Grand Concourse Line, a key commuter line linking the Bronx with Manhattan.
L.K. Comstock provided electrical services totaling $83 million and civil architectural services totaling $15 million. This work included replacing the existing electro-mechanical-based signal system (circa 1933) with conventional fixed-block technology. L.K. Comstock constructed and installed signal equipment in a new master signal tower, five relay rooms and a central instrument room and signal power room. The project was completed in 2007.
