Further progress on the development of the Communications Based Train Control (CBTC) system on the Queens Boulevard Line connecting Queens and Manhattan in New York this week with the announcement of who has been awarded a $223.3 million contract. The radio-based CBTC technology provides real-time data on vehicle position and speed conditions, allowing system operators to safely increase the number of vehicles on a rail line. This results in greater frequency of train arrivals and allows the MTA to accommodate more passengers on its system. The winner of the contract is L.K. Comstock & Company Inc., a leading specialty electrical contractor and a subsidiary of RailWorks Corporation and work on the project begins this month and extends 55 months with a targeted completion date in the fall of 2021. The hardware for the line is supplied by Siemens and Thales, as reported by SmartRail World in 2015, with L.K. Comstock performing all of the signal systems upgrades, CBTC installation and new systems work.
The CBTC technology reduces the amount of wayside equipment and, as a result, reduces maintenance costs and service disruptions. Additionally, the technology precisely locates each train on the tracks and controls speed, improving safety for riders and employees.
RailWorks Transit will serve as a subcontractor to perform related track and civil work. Both companies are subsidiaries of RailWorks Corporation. L.K. Comstock is responsible for installing new signal, communications, fiber-optic and CBTC systems as well as track on the mostly four-track system starting in Jamaica, Queens, and extending under Queens Boulevard to 8th Avenue and 50th Street on the west side of Manhattan.
Additional project work consists of building new signal rooms, modifying existing facilities and upgrading systems to ensure connectivity with the CBTC system. The project also includes constructing and extending fiber backbone support to perform health and system tests on the CBTC rail stock in all the ancillary yards and facilities that support the Queens Boulevard Line.
L.K. Comstock is the only MTA contractor to install CBTC technology on New York City Transit Authority projects, including the current Flushing Line and the completed Canarsie Line CBTC signal modernization projects. The Queens Boulevard project is part of the MTA’s $29.45 billion, five-year capital plan from 2015-2019, which commits to modernize the New York City Subway system with a moving block signal system.
