Suspected vandals broke into a parked B train Sunday night, one of several subway vandalism incidents reported on the eve of Monday’s blizzard.
Sources tell the Daily News the unidentified trespassers broke into the train while it was parked on the express track at the 174th-175th St. Station in Tremont and moved it a few car lengths.
Somehow, sources said, the vandals also damaged the train car’s master door controller — the control panel that allows a train operator or conductor to open and close the train’s doors.
The trespassers, described as “kids” by sources, were seen on the train by a transit worker, but fled before they could be confronted.
An MTA spokesperson did not immediately respond to questions about the train’s condition and whether it was still in service.
Sources told the News the Bronx break-in was one of several apparent vandalism incidents in the subway system between Sunday night and Monday morning.
Graffiti was reportedly found overnight on parked subway trains at the 174th St. Yard under Washington Heights serving the C train, as well as at the 240th St. Yard of the No. 1 train near Van Cortland Park.
Sources also told The News a number of trains parked on a layup track near the Bowery Station of the J and Z trains on the Lower East Side were tagged Sunday night.
Trespassers, especially young ones, breaking into parked trains has become a persistent issue plaguing the subway system in recent years.
Two months ago, a thief stole the control stick from an R train parked under south Brooklyn — the same section of track where a repeat-train-thief callously threw a train in reverse during a joyride months earlier.
A teenage crew gained notoriety last January for breaking into a pair of R trains and moving them at speed along a section of express track in Brooklyn.
