Signal upgrades on MBTA’s Red and Orange Lines are expected to improve service reliability.

LTK Engineering Services is proud to be part of the team that is providing program and construction management for the Massachusetts Bay Transportation Authority’s (MBTA) infrastructure improvements project on its Red and Orange Lines.

MBTA recently awarded a design-build contract to Barletta Heavy Division to update the signal systems on the metro lines. LTK developed the specifications for the modernization of all signal control and communication equipment on the lines, which will increase reliability, maintainability, and flexibility while improving system capacity.
