Millions of New Yorkers take the subway.

Many others can potentially sleep on it, including James Edwards and Luis Terranova.

“Not the train, but the platform,” Edwards told us this week. They explained not every station is locked — so they can sleep on the platform each night.

They have been homeless for years — in and out of the city’s shelter system.

Together, they’ve been arrested dozens of times — mostly for petit larceny. They use K2 — a synthetic marijuana.

When we met them, they had just emerged from the E train.  

They welcomed the news of the subway reopening 24/7.

“I’m excited because it means, you know, we can ride all night and we don’t have to stay out in the heat all day and stay out in the cold all day, you know what I mean,” Edwards told us while standing on the subway platform.

Since Gov. Andrew Cuomo announced this week that the subway would be returning to 24-hour service, he has dramatically argued one point repeatedly — homeless people should not be allowed to sleep on the train.

“This is how we treat people?” Cuomo asked on Wednesday. "They sleep in the subway system and we say that’s ok. I don’t accept it. We need the NYPD. We need the same intervention. You’re not going to stop the trains, so you’re not going to have that interval. I argue you can do it without interval."  

When the subway shut down last year, the city immediately created a new system at stations at the end of the line — shuttle buses took people to shelters if they were willing to go.

Over the last year, the city has referred thousands of people to shelters from the trains when they shut down at night. The city says, of those thousands, 826 are still in shelter and no longer sleeping on the trains.

The question is when the trains come back on full steam and people experiencing homelessness can ride all night, will the city still be able to persuade them to come inside?

“I don’t think we are going to see any legitimate change in the circumstances of folks who are spending time on the streets or on the subways without investment from the mayor and the governor in what we have been calling for for months and years, which is access to single occupancy hotel rooms to provide dignity and safety to those on the streets,” said Giselle Routhier of the Coalition for the Homeless.

When the subway does turn back on, NY1 has learned the city plans to continue providing shuttle services to shelter at some end of line stations. A spokesperson also said the city will target eight subway stations for more intensive outreach throughout the day and night.

Edwards and Terranova both said they plan to stick with the train.
