The emergency-brake-yanking scoundrel who has been scuttling subways during rush hour is responsible for hundreds of commute-crushing train delays since March alone, according to a report.
The rail reprobate, who sources say has been using an MTA master key to sneak into conductor cabs and grind trains to a halt, has caused 747 delays or cancellations in the last three months, Jalopnik reports.
His subway-stopping antics caused bottlenecks that rippled through the system and caused delays on other trains, the report said.
The MTA is investigating “dozens of incidents” since the beginning of the year, officials confirmed to The Post.
In some instances, he was able to delay more than 100 trains in a single spree, Jalopnik reported.
Incident reports shared with The Post show just how nefarious the subway saboteur can be.
In one instance, on May 15, he managed to personally cripple two trains within two minutes of one another, the papers show.
At 9:10 p.m., he slinked aboard a southbound No. 2 train at Brooklyn’s Winthrop Street station, unlatched security chains on the back car and popped open the storm door to gain entry to an empty conductor cab, where he pulled the emergency brake and scampered off.
While the train’s conductor and motorman were scratching their heads over the inexplicable stop, the rogue was tearing over to a northbound train at the same station — which he halted at 9:12 p.m., records show. The M.O. was the same: He unchained a back door, cracked it open and yanked the brake before vanishing.
Regular service resumed 10 minutes later, but the damage was done.
Police released security footage of the suspected delay-causer Thursday showing the man — wearing a black shirt with red and white letters that read, “SWAG DON’T COME CHEAP” — riding on the outside of a northbound No. 2 train near 14th Street and 7th Avenue on Tuesday night that was later delayed when he pulled the e-brake.
The NYPD is investigating the pattern, and NYC Transit chief Andy Byford on Wednesday pledged: “We’re going to hunt them down. We intend to nail them.”
