Management still have their heads in the sand over the cracked wheel sets on the Piccadilly line. They've had the whole fleet checked now, but don't seem to think there is a need to check them again in the foreseeable future.
Instead, they have a cunning plan. If the driver hears a loud bang, then a member of station staff will ride with the driver until the train can be put away. Oooh, we can spot the flaws in that!
Management obviously have short memories, and in particular seem to have forgotten the events leading up to the Chancery Lane derailment. The driver reported a worrying noise on the train, but it was kept running until it could be put away and promptly came off the rails before it got there.
Oh, and if LUL thinks it has spare station staff hanging around available to jump on trains at the drop of a hat, then they obviously haven't read the rosters recently.
