The MTA’s plan to modernize indicators on the G prepare will take longer than deliberate, transit officers mentioned Monday, with an anticipated months-long delay to replace tools on the subway system’s latest prepare vehicles.
Transit officers mentioned Monday that the radio transceiver system used to find trains on the L line, the No. 7, and parts of the F prepare — the signaling system often known as Communication Primarily based Prepare Management system or CBTC — is already rising out of date. In consequence, the re-signaling efforts underway on the G line shall be delayed as work begins to retrofit even the most recent prepare vehicles to make the most of newer 5G transceivers.
“That will take longer than the work we are doing on the G [line] itself,” Jamie Torres-Springer, MTA’s building head, informed the company’s board Monday. “Putting CBTC into full operation on the G line overall will take longer than anticipated, but there are no additional disruptions to riders associated with this.”
The G prepare — identified in transit-speak because the Crosstown Line — has been present process main renovations for greater than a yr. The method concerned main outages final summer time, and scattered night time and weekend outages this summer time.

In the meantime, officers quietly moved the most recent prepare vehicles, the R211s, onto the tracks of the G final month.
However even these vehicles, contemporary out of the ultimate meeting facility in Yonkers, wouldn’t have radios new sufficient to speak to the signaling system MTA’s building group is constructing beneath Brooklyn.
Officers mentioned Monday that the wi-fi community at the moment in use on CBTC traces just like the L, the No. 7 prepare, and parts of the F is already sufficiently old that they aren’t assured that producer Siemens will proceed to supply help or spare elements for very lengthy into the long run.
“When we started off Crosstown, we realized nobody is developing the communication system,” mentioned MTA’s deputy chief improvement officer Mark Roche. “Siemens, who designed it and provided it, no longer even invests in it — there’s no updates to the software, there’s no updates to the hardware.”
“We made the decision at the beginning of Crosstown to change the communication system.” Roche added. “The fact that we made the decision to build the program properly is going to make that project slightly delayed.”
The MTA board’s Capital Program Committee voted Monday to approve a $47 million modification to a contract with Hitachi on Wednesday that may pay the agency so as to add up to date 5G wi-fi radios to the system’s R211 prepare vehicles.
Torres-Springer and different MTA officers characterised the delay as small. CBTC is predicted to return on-line north of the Hoyt-Schermerhorn station by the top of 2027, and between Hoyt-Schermerhorn and the southern G prepare terminal at Church Ave. by the top of 2028.
In it’s month-to-month report Monday, nevertheless, engineers with Michael Baker Worldwide, the MTA’s unbiased engineering marketing consultant — tasked with providing an unbiased evaluation of the company’s capital initiatives — estimated the challenge may very well be delayed into summer time 2029 if third get together contractors like Hitachi couldn’t meet their deadlines.
