Here's a recent article in Wired that indicates that they've been swabbing since late March and don't seem to have found the virus on the subways:

And as for the subways? Mason’s team has found plenty of genetic material from humans, the flu virus, and some bacteria, but so far, no sign of SARS-CoV-2. That’s good news, he says, and probably reflects the enhanced cleaning and disinfection the Metropolitan Transit Authority enacted in mid-March. As MTA starts making plans for how it will reopen the subway once state officials relax stay-at-home orders, Mason hopes his swabbers can help the agency respond more nimbly to head off potential new outbreaks. Regular environmental sampling could flag surfaces that need more thorough cleaning and aid the city’s forthcoming army of contact tracers. It could also allow city officials to partition public spaces into zones that are safe for people to enter and ones that have a high risk of infection, rather than just keeping everything shut down.

So contra Marty's unsubstantiated claims, it seems the MTA has been protecting its citizens from picking up SARS-COV-2 on seats, handrails, etc.
