Police say 61-year-old Gian Verdelli, of Brooklyn, groped two women on the PATH train earlier this month.
An undercover sting operation was put together after the two women reported being harassed.
Verdelli's arrest record dates all the way back to 1970.
Police identified him by using a cell phone photo one of the victims, 28, took of her alleged attacker after a July 3 incident. She said the same man had also groped her on June 30.
Verdelli is charged with two counts of criminal sexual misconduct and possession of marijuana and drug paraphernalia.
Verdelli was being held without bail, and it's not known if he has retained an attorney.
