Human error sparked Monday morning mayhem on 7 line — but MTA finds silver lining in situation

The MTA discovered the source of an issue that caused the 7 train – among 13 other lines – to experience hours of delays Monday morning.

Sally Libera, senior vice president of subways at New York City Transit, told reporters that afternoon that not only was the signal malfunction resolved, but also the system worked just as planned.

When a signal transponder was misplaced during weekend work between 42nd Street – Grand Central Station, all trains on the line began running further apart to prevent a collision, Librera said.

“We’ve confirmed the cause of the incident [Monday] morning — it was an isolated case of human error … In order to do track work, we removed a transponder. When we returned it, we returned it to the incorrect location,” Librera said. “Our signals weren’t able to correctly identify the placement of the train and they appropriately slowed the trains down and spaced them farther out so we could operate safely. Our signaling system worked exactly how it’s supposed to work.”

The misplaced transponder was found 100 feet from where it should have been installed, and was further into the East River tunnel than expected.

The MTA is now conducting a full investigation to determine how the human error occurred so further problems can be avoided in the future.

The 7 train is somewhat new to the Communications-Based Train Control (CBTC) having only been installed with the digital signaling system earlier in 2019, but this would seem to be the first reported incident such as this that the MTA has publicly attributed to a misplaced transponder.

But not all delays were related to the issues with the 7 train.

Librera said the 7 train’s woes were not connected in to other lines affected by a switch problem at 36th Street in Queens on the M and F lines.

“That compounded the issue for our 7 line customers who may have transferred to the 7 line at Roosevelt for service into Manhattan, “ Libera clarified.

Riders Alliance policy director Danny Pearlstein called for Governor Andrew Cuomo to enact a congestion pricing plan, which he proposed in 2017 and which was authorized in the state Legislature in 2019.

“[Monday] morning’s citywide signal meltdown is an unacceptable reminder of how far Governor Cuomo still has to go to fix the subway. Once again this new year, New Yorkers look to our governor to put transit reliability at the top of his agenda,” Pearlstein said. “Congestion pricing is coming, the MTA has a plan to modernize signals, and the governor needs to make it all happen on time.”
Cuomo went public with his support of congestion pricing in late 2017 before releasing a study that recommended an $11 fee on cars entering Manhattan below 60th Street during peak hours. Those funds would be lock-boxed to go toward modernizing the city’s subways and buses.
But advocates are still pushing for the implementation of the toll yet a year after the Cuomo announced in his 2019 State of the State address.
Cuomo’s focus on Monday morning was on the announcement of a massive overhaul of Penn Station into the Empire Station Complex.
As of January, the MTA is now working with a $52 billion four-year capital plan.
