The MTA plans to clean trains and stations around the clock, not just during four-hour overnight closures beginning next Wednesday, interim transit president Sarah Feinberg said Friday.

“The cleaning is going to be happening 24 hours a day,” Feinberg said during an interview with PIX11 News. She said riders will notice the increase.

“We’re closing between 1 and 5 to make sure we hit everything at least once, and probably multiple times, but the cleaning is going to be happening 24 hours a day,” she said.

“You’re going to see 10 or 12 cleaners board the train and do a quick disinfection, a cleaning in the terminal before it takes off again.”

Daily ridership between 1 a.m. and 5 a.m. during the coronavirus pandemic is around 11,000. The MTA has said for-hire car services like Uber and Lyft will play a role in any replacement service.

On Friday, Feinberg revealed that the MTA also plans to increase service on existing bus routes to match overnight train frequencies, and may run shuttle buses for the outer boroughs.

The cash-strapped MTA, which is seeking a $3.9 billion federal rescue, will pay for the increased cleaning and extra transit options, though Feinberg did not provide a price tag.

Despite the cost, Feinberg said the unprecedented decision to shut down the subway system every night was necessary to address reports of homeless encampments on trains and platforms.

“We cannot clean the trains and stations the way we want to and the way we need to while this continues to be an issue,” she said.

“We’re going to be paying for those extra services, and it’s important that we do so.”
