Manhattan Borough President Scott Stringer is calling on the MTA to do more to prevent subway deaths.

Stringer said four fatalities were reported at subway stations over a 24-hour period last weekend, though the circumstances of those deaths are unclear.

There were more than 50 deaths last year, but at this rate, Stringer said there will be at least twice as many in 2013.

Stringer, who is running for city comptroller, wants the MTA Inspector General to look into the cost of improved safety features like signs, audio warnings, and platform barriers or safety doors.

"We're obviously very troubled by these deaths," Stringer said. "There's something visceral and something tragic when we hear that somebody perished on a subway track or someone was hit by a train. It disrupts the life of a city because it's a tragedy of immense proportion."

MTA board member Alan Capelli, who joined Stringer at the press conference, said rider safety is the top priority, and the agency is willing to explore all options.
