DOOR DEVICE FOR RAILROAD CAR, RAILROAD CAR HAVING THE SAME, EMERGENCY DOOR UNLOCKING DEVICE, AND METHOD OF UNLOCKING DOOR BODY LOCKED WITH LOCKING MECHANISM
A door device with a locking mechanism includes an operation member that is operated to unlock a door body. When a power supply for a railroad car is normal, it is determined whether the door body is allowed to be opened by operating the operation member. The door body is unlocked only when it is determined that opening of the door body is allowed. Whereas when the power supply for the railroad car is in an abnormal state, the door body is unlocked by the locking mechanism by operating the operation member.
