The best-laid subway rescue plan may have to be tweaked. NY1 Transit Reporter Jose Martinez has more on that story.

The first phase of the MTA's emergency subway rescue is on the move.

"We've addressed over 1,500 track defects," MTA Chairman Joe Lhota said at a press confence Wednesday. "In July, we cleaned over 120,000 pounds of dirt and trash from the 8th Avenue corridor."

Aging subway cars are getting more frequent tuneups, as are decades-old track signals.

But just months after the nearly $840 million plan began, it may have to be scaled back.

At least that is the message MTA officials are now sending in yet another attempt to pressure Mayor Bill de Blasio into ponying up half of the money.

"I would have thought that he would have cared as much as others would have cared about making sure the system got back to a better state of reliability," Lhota said.

But the mayor has said, in effect, it's not his problem, pointing out that the MTA is a state authority that is run by a board for which the governor has more appointees than the mayor.

In a statement, a City Hall spokesman said, "City riders won't allow the state and the MTA to pull the wool over their eyes. Implementing half the plan isn't an option."

The spokesman went on to say that for the sake of the subways, Gov. Andrew Cuomo should restore close to a half-billion dollars in MTA funds diverted to the state budget since 2011.

One of the mayor's appointees questioned Lhota's warning.

"The scenario it sounds like you're setting up is, 'I'm going to present what my revenue plan is. If the city doesn't pick up half of it, I just throw half the plan out the window,'" said City Transportation Commissioner Polly Trottenberg, who is an MTA board member.

Lhota said he'll present next month a list of what repairs the MTA might put off because of the funding gap.

If he ultimately fails to wring more money out of City Hall, Lhota said the MTA will have to do what it can with what it has.
