⚠️ @ldnoverground have announced they are carrying out extra safety inspections to their trains, therefore some lines are closed. London Overground routes affected are between Highbury & Islington to West Croydon/Clapham Junction/Crystal Palace and New Cross.
Thameslink's tweet above isnt the full story....

I understand that specifically, it was a brake caliper was found on the track at Shoreditch. |

Safety checks have been completed and the remainder of the fleet is now heading out.

Safety checks have been completed and the remainder of the fleet is now heading out. So does the use of the word "remainder" suggest that the unit with a missing caliper has been found and is now receiving remedial attention. As brakes probably rank high in the eyes of any rail safety body - presumably as part of Network Rail - RAIB would at the very least monitor developments. In the interim I assume the maintenance records, for at least the affected unit, will be checked to see when that component last had attention and determine if that intervention might have contributed to it becoming detached or if a design flaw lies behind this incident and might be a prelude to the whole fleet needing modifications to prevent a recurrence. |

All we know at the moment is what has been reported. It’s a bit premature to speculate whether it’s a potential fleet issues, and as per our forum rules, we don’t speculate anyway in these type of things.

I'd be amazed if it were a design flaw. AFAIK the bogie on the 378 is common to all types of electrostar and has been around since the late 90s, and has lineage beyond that to the early 80s (in the form of the BREL T3 bogie) and potentially beyond. If it were an actual design flaw with the bogies (as opposed to maintenance regimes etc not being followed), it'd have shown up by now. |

If the calliper falling off caused, or had the potential in slightly different circumstances, to cause a serious incident then the RAIB will need to be informed although the timescale for doing this varies depending on a few factors (the details are on their website). The ORR will also be interested I expect.
However, based on what is in the public domain so far, the actions taken are exactly what should be done in a reactive situation so I don't expect to see any further action on that score from either the safety regulators or the unions.
Either concurrently with the checks or shortly afterwards there will be an investigation to determine exactly what happened, why it happened, and what allowed it to happen. When that is known, then the investigation will look at what (if anything) can be done to prevent it happening again, and/or to detect it sooner if it does. It is almost certainly far, far to soon for anybody to know that yet though and until they do it is not possible to state what actions can or will be taken by who. Depending on the complexity of the issues involved then it might take anything from a couple of days to many months to get to that point.

Indeed. If there was any hint of a serious fleet wide issue, the trains would not have been put back into service as quickly as they were. Recalling the Chancery Lane derailment, this led to a complete withdrawal of 1992 stock until urgent renedial work was done, which took months to fully complete. I’m not seeing anything along those lines with the 378’s.
