So yesterday, I had 455 828 on a peak Caterham to Victoria service and I was just about to board the last carriage, when suddenly, the rear DTSO stopped and I saw that the lights were switched off and there was a "Defective door" sign, so I had to make my way to the next carriage which was absolutely packed.
But my questions are, how do they manage to turn off the lights in one carriage but not the whole unit and why would they take an entire carriage out of use? If its for a defective door, can't they just lock that door out of use and passengers can use the next set of doors in the carriage? I have yet to see something like this on an SWT Class 455 (don't know if they even do it) but this is the fifth time now its happened on one of Southern's units and It always seems to be the DTSO that is locked out. Couldn't they have taken the unit out of traffic if an entire carriage could not be used, as they cannot split the unit and leave one carriage in the depot as that will reduce capacity. 42 out of 46 455's are diagrammed in traffic for Southern so one of the three spare units (455 845 out of traffic) could have taken over 828's duties.
