The Siemens though will cut the power again and revert to "limp home mode" on door failure. This means the driver has no choice but to manually close to door or to proceed without passengers as who would stay on a train doing 30km/h.
The door system on the Siemens is much more "secure" than the X'Traps where you can manually isolate the entire door relay and still operate the train.
If you isolate the doors on a Siemens by use of the curcuit breaker - it automatically detects a failure and reverts to safe mode. The only true bypass is to lock each door so it "closes" the curcuits off for each of the door sets - and this means the doors are closed anyway. |
