Things went off the rails at a meeting in Manhattan Thursday where MTA chairman Joe Lhota was set to discuss the future of the city's crumbling subway system.

He was poised to speak at the "Only in New York" Event at the Museum of the City of New York in East Harlem.

But instead, the session was taken over by disability rights protesters.

Members of "The People's MTA" have been fixtures at recent MTA meetings, pushing for more elevators throughout the subway systems' 472 stations.

"Of course it advances our cause it shows the amount of concern, consternation, frustration."//"We shut down the MTA's attempt at a PR show," said one protester.

Only about a quarter of subway stations are accessible to riders with disabilities.

MTA board member Veronica Vanterpool, who also attended the event, said that many members have already been raising the issue of accessibility.

Earlier this week, the MTA agreed to make five more stations compliant with the Americans With Disabilities Act.
