Thanks for the interesting, full explanation. No doubt the points here and elsewhere are regularly inspected for signs of any potential "spread." If you have the opportunity to watch the Channel 5 program on Paddington Station, you will see an HST derailing in platform 2 due to track spread. It took best part of 2 days to repair. In this case it was due to the rotting of the longitudinal wooden baulks to which the rails had been fixed.

I mean, what kind of commentary can one even make on that? Its just laughable. How is there a maintenance management and liaison system in place such that this hasn't come up to be checked, verified, or confirmed before??? Wasn't there a brief alliance between SWT and NR at one point - how did their managers not routinely go over such details as part of their own contractual stuff? What about when TfL got part privatised - how did the infraco get its details wrong?
Embarrassing - presumably there has been a flurry of paperwork since redefining in excruciating detail to everyone relevant where the demarcations lie in responsibility, but will anyone take responsibility for oversights and mistake, in addition to salary.

One thing is not correct regarding the track certification
If on LU Traction then LU certification is required - Putney Bridge signal WG13 roughly on the westbound and on the eastbound just off the platform ramp at the west end are the traction section gaps.
If on NR Traction then NR certification is required - PTS (Personal Track Safety) as a minimum if walking alone but COSS (Controller Of Site Safety) if working and walking in a group.
So Wimbledon is under NR for track certification so them saying that and quoting that is incorrect
Whilst LU do the track maintenance entirely they do have both LU and NR track certification

What does "NR Traction" actually mean? The platforms used by the District line definitely have to have third and fourth rail electrification, so in that respect an understanding of the dangers associated with the extra electrified rail is absolutely essential. So does that make Wimbledon LU-used tracks on "LU Traction"? Or is that more to do with who actually provides the power?

Its who provides the traction current for that area, the Wimbledon branch west of Putney Bridge is fed from NR controlled by Raynes Park control room

These things happen Ben! It's a big bad universe out there.....

despite re-sleepering, new rails and ballast, the track concerned still hasn’t been used since the incident.
Still trying to work out who owns what?

The RAIB report seemed to say that ownership was not in doubt - it was responsibility that was uncertain.

The extra 'electrified' rail isn't electrified on NR territory - it is at earth potential, and connected to the running rails to return the traction current. The positive rail is at +750 volts.

This morning, for the first time since November, I noticed the rail heads on the up link line are no longer completely rusty. Has it finally been brought back into use?
