Engineering locomotive derailed on points at the Hainault end of the depot around 02.30, will require heavy lifting crane to recover.
18 service trains stranded within depot, reduced services operating.

In addition to this there is also some sort of failure at Leytonstone!

I commuted home to Roding Valley via Hainault earlier this evening, and passed a single wagon just outside Hainault that looked like it was in the process of being re-railed. It looked like it had lots of blocks underneath it, and there were lots of people with orange high vis vests.

Battery loco was rerailed around 1315.
Two other wagons were damaged in the derailment one with a bogie that required changing.
This was completed at 02.40 this morning.
Damage to pointwork assessment being undertaken.
15 trains cancelled today, Wednesday.

Why were so many trains trapped? Hainault Depot has access at both ends so one end should still be available?

Traction current had to be isolated to effect recovery of derailed loco and wagons and to repair damaged points and power rails.

I take it then that it's not practical to clear the site, energize the current, move a couple of trains out, then discharge again? That would get a few more trains on the line.

If the derailed loco is shorting on the current rail it won’t be possible to recharge that section.

Is the derailment of an engineering train within the boundaries of the depot something that the RAIB would investigate?

If the derailed loco is shorting on the current rail it won’t be possible to recharge that section. However, the loco had already been rerailed and nothing suggests that other stock was entangled with the current rails.
That said, work on the points would require discharge, but clear-site/recharge/move trains/discharge & make safe/resume work could still presumably happen.

Presumably that would take a lot of effort, for what?
Just to keep trains running?
No point. Just cancel...

Is the derailment of an engineering train within the boundaries of the depot something that the RAIB would investigate? I believe not, although looking I've not found anything that explicitly says so. The RAIB's quick reference guide to notification mentions derailments only once: "Derailments on lines open to traffic or which block running lines open to traffic" and the word "depot" does not appear in that document. Schedule 1 of the Search Legislation The Railways (Accident Investigation and Reporting) Regulations 2005 states a requirement to notify the RAIB of "A derailment of rolling stock on a running line that was open to railway traffic at the time of the derailment, or which blocks a running line that was open to railway traffic at the time of the derailment." In the regulations "running line" is defined as "a railway line which is not a siding and is ordinarily used for the passage of trains or tramcars"; "siding" is not defined. |

Is the derailment of an engineering train within the boundaries of the depot something that the RAIB would investigate? It might not be something the RAIB would investigate but it's probably notifiable. In quite a few instances they appoint an Accredited Agent to undertake assessments and preserve evidence whilst the Investigator is on their way to site. I have also known of incidents which are notified but they and the ORR don't initially get involved, but keep a close eye on the situation and have the right to intervene if they feel appropriate later. |

There's a nagging thought in my head that suggests it might be reportable if it causes passenger delays... but that may well be "7. An accident or incident that is likely to result in suspension of a railway service for a period in excess of 6 hours." that I'm thinking of which may not apply here as I don't believe it was suspended.
