【正文】 leftovers (剩飯 ) in the microwave. What most passengers don’t realize is that their minute is already there. Every muter 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. In other words, if you think you have only a minute to get that train — well, relax. You have two. The courtesy (禮貌 ) minute, in place for decades and published only in private timetables for employees, is meant as a grace period（寬限期） for those who need the extra time to get off the platform and onto the train. “If everyone knows they get an extra minute, they’re going to waste time doing unimportant things,” explained Marjorie Anders, a spokeswoman for the MetroNorth 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 downtothesecond accuracy. The railroad industry helped invent the concept of standard time, and time zones were established in the United States in the 1880s, 35 years before they were written into law. And most muters know their train by the precise minute it departs. The trains quickly make up the minute: at all other stops, the public timetable prevails. The phantom minute does not exist at muter railroads in Chicago, Los Angeles, Philadelphia, or San Francisco. But in New York, the secret minute dates back decades. “That’s been done forever, from my knowledge,” said Jack Swanberg, 70, an unofficial historian of MetroNorth. “I was the trainmaster starting in 1970 and I’m sure it’s been the case since 1870 for all I know.” 64.
