It can be, but depends on the location of the faulty doors.It isn't, I believe that if 2 doors next to each other on the same side are locked then the train gets taken out of service .
Normally you'd lock a coach out and be done but on 700s its not possible so the whole train is taken out.
As I said before the first class can be locked out but that is it. There is fire doors but they wouldn't be used in that scenario
You can use the internal fire doors to lock of coaches 9-12, or 4-12.
