Gate Time Travelers

It’s like the customary several-minute delay for the curtain to rise at theaters, only more helpful:

Every commuter train that departs from New York City — about 900 a day — leaves a minute later than scheduled. If the timetable says 8:14, the train will actually leave at 8:15. The 12:48 is really the 12:49.

In other words, if you think you have only a minute to get that train — well, relax. You have two.

The phantom minute, in place for decades and published only in private timetables for employees, is meant as a grace period for stragglers who need the extra time to scramble off the platform and onto the train.

“If everyone knows they get an extra minute, they’re going to lollygag,” explained Marjorie Anders, a spokeswoman for the Metro-North Railroad. Told of this article, Ms. Anders laughed. “Don’t blow our cover!” she said.

Entirely hidden from the riding public, the secret minute is an odd departure from the railroad culture of down-to-the-second accuracy.

. . .

The minute was originally known as “gate time,” dating to the days when gates were used to block off the ramps that lead down to the platforms. (The gates are still occasionally used at Grand Central.)

At the publicly posted departure time, the gates would be closed; those who had already made it through would have a minute to climb onto the train.

The practice gradually extended to trains to Long Island and New Jersey that start in Pennsylvania Station and the Long Island Rail Road’s Brooklyn terminal.
