Most subway accidents result from slips, trips, and falls on stairways when someone is in a rush. The best safety advice we can give you is: slow down when you are on the stairs, and hold the handrail(扶手).

Some trains are shorter (that means they have fewer cars) when it’s the not rush hour because there are fewer passengers using the subway. Some short trains operate without a conductor. On those trains, the train operator opens and closes the doors, makes station announcements and helps customers, if needed. At most stations, there are signs that read: During Off-Hours, Trains Stop Here. If you stand near the center of the platform near the sign, you won’t have to rush when the train arrives.

While you’re waiting, please stand behind the yellow protective strip, away from the platform edge. No matter what situation arises, keep off the tracks. Tracks contain 600 volts of live electricity. If you drop something on the tracks, go to the station announcer room and tell the agent.

Boarding between subway cars may seem like a time-saver, but it is highly dangerous. It’s also dangerous to try to keep subway doors from closing when you are entering or exiting the train. They are not like elevator doors and will not reopen automatically. In addition, make sure that pocketbooks, clothing, packages, umbrellas and other personal items are clear of the closing doors. When you’re inside a moving train, never run between cars or lean against doors. When you are standing, always hold on.
