NYC Transit tackles signal system challenges with training and upgrades
The light you see from the platform is part of the signal system that keeps the trains properly spaced on the tracks and prevents crashes.
More Local News
Inside NYC Transit Signal School, crews are trained on the system. It's located underground in a station complex under 14th Street in Manhattan.
Signal crews are in training for about five months in the classroom and in the field.
Signal maintainers learn how the mechanism works, how it operates, and what can go wrong. Most of the signal technology is about a century old, and some of the parts are 60 to 70 years old.
NYC Transit President Demetrius Crichlow started with the MTA 28 years ago as a signal man.
He celebrated his anniversary with a visit to the training center on Wednesday.
He spoke with class members and discussed the challenges of the system.
'It's never just the bulb in the field. It's a complicated system of old relays and track wires that tie into them. They don't know what's causing a failure. We have different crafts to identify the problem and get the right tools there,' he said.
NYC Transit stages response teams in busy areas or places with complex operations.
In 2009, signal technology was introduced along the L line. Communication Based Train Control (CBTC) is also installed currently along the 7 line. The upgrades allow more trains to run.
Maintainers and signal crews are trained in the old and new systems.
Projects to install the new signals along the Culver Line in Brooklyn and along the Queens Boulevard line have been funded.
More than $5 billion of the next $68 billion capital improvement plan would be spent on new, upgraded signal technology.

MTA project to modernize subway line could be millions over budget and years late: report
The Metropolitan Transportation Authority will end up $91 million over budget on a project to modernize a portion of the subway system, a new report said — but officials said everything's going to plan even though it may be years behind schedule. The project for the crosstown train, or G line, could be as much as two years behind schedule as the beleaguered Big Apple transit system works to upgrade its signal system across numerous routes that even include newer trains. The latest 5G technology for the communication-based train control (CBTC) would provide faster and more dependable service, MTA officials have said – as riders face a possible fare hike next year. Advertisement 3 The Metropolitan Transportation Authority is a whopping $77 million over budget to modernize a crucial subway line, an independent agency insisted this week — as the technology on newer trains is already becoming useless. Luiz C. Ribeiro for New York Post 'Not every project that we've done in the last five years has been on time and on budget,' MTA chief Janno Lieber said during a press conference Wednesday about the possible additional expenses and delays. Costs attached to the G line could balloon to as high as $715 million instead of the $624 million pegged by the MTA, an independent engineering consultant stated in a report delivered to the MTA board Monday. Advertisement But that estimation from the IEC is in sharp contrast with the MTA's own internal projections, which still has it running on budget. The F line in Brooklyn is expected to overrun costs by $22 million while the Queens Boulevard line could blow roughly $28 million past budget, according to the report. But the MTA stated it believes those projects are either under budget or in line with the spending plan, when using its own projections. 3 The plan to revolutionize the G line is currently two years behind schedule. Robert Miller Advertisement The independent consultant also stated all of the revamped lines won't be wrapped up on schedule. The G line could be done by 2029 instead of 2027 with MTA construction head Jamie Torres-Springer stating any extended timeline can be attributed to the CBTC technology that needs to replace 4G tech that are even on newer trains. 'While all of the physical work to outfit the G train is going smoothly and is on time, a new technology that we need to adopt for CBTC across all of our subway lines,' he said, 'not just for the G train, but starting with the G train, it's a 5G radio that would be on subway cars to replace obsolete radio equipment, and that will take longer than the work that we're doing on the G itself.' 3 MTA officials said that with 5G technology for the communication-based train control (CBTC), it should result in faster and more reliable services for subway lines such as the G and other train lines across the system. Annie Wermiel / NYPost Advertisement Work on the G line has led to some travel headaches for commuters this summer after disruptions were even worse last year, though further outages were not expected to handle the signal swap, Torres-Springer. The F line in Brooklyn would be done by September 2025 – three years later than the initial completion date while the A, C, E lines on Eighth Avenue will be finished by 2027 and the Queens Blvd line won't be done before 2028 – that would make both projects two-years late, according to the report. Lieber, in his Wednesday press conference, said the agency was not shying away from the delays while stressing the pushing out the projects will lead to more benefits. 'But we own every time we run late or we run over budget, we'll always highlight the fact that we've made a lot of progress on big projects on that,' the MTA chief said in response to the independent report. 'And we will continue to push forward on these projects that are really important. And you see, we funded a lot more signal work in the coming capital plan.'
