What happens to them? I mean, what happened to the one involved in the
Chancery Lane derailment?

The undamaged part of the train is back in service, however the rear four cars have been sent to Adtranz Crewe for repair.


Is it back in use? And what about the
derailed Piccadilly and Northern trains, what's going to happen to
them?


Dunno, presume the Picc one probably wasn't that badly damaged, and will simply be out of service for a few weeks or months. As for the 95ts, cars involved in similar derailments (e.g. Piccadilly Circus) have been scrapped, though with the superior crashworthiness of the 95ts, it's quite likely that the car(s) concerned will be repaired, probably by an external contractor.
