#MTA faces glass shortage amid subway train window-smashing spree

A spate of over 400 smashed subway windows in four months has the MTA on the verge of a glass shortage, transit officials said Friday.

“We had a reserve of glass when this wave started in May. We’ve run through the reserve,” MTA spokesman Tim Minton said of the rash of vandalism.

Since May 14, transit workers have reported 31 separate instances of broken windows on the 7 train, internal records obtained by The Post show.

Smashed windows have also turned up on the 2 and 3 trains, MTA safety exec Pat Warren said — costing the agency more than $300,000 so far.

“While there’s vandalism across the system at any given day or time, this recent rash of windows appears to be consolidated in a couple of lines,” Warren told The Post.

“With the MTA being in the financial condition it’s in, that is not a worthwhile thing for us to be putting money towards.”

Video posted from last Saturday shows cracked glass on a succession of doors and windows on a 7 train in Queens. The MTA said 39 individual windows were destroyed in the incident.

The glass-smashing has led to 61 train cancellations and over five hours in cumulative train delays, according to MTA records.

“Any train that’s broken, it has to be taken out of service,” Warren explained.

“That means that at any given time in the short term, our customers are going to be short a train, which means they’re going to have more crowded conditions.”

Officials warned more service impacts could be coming due to delays in acquiring replacement glass.

“We’ve been resupplying, but the manufacturer has had difficulty keeping up with the extent of the vandalism that we’ve seen,” Minton said.

“We’re not at a point where there could be a service impact, but that could change.”
