Surprised no-one's mentioned this yet but the OHLE came down in the Biggleswade area this afternoon, with all lines blocked. As well as no trains between King's Cross and Peterborough no trains were running to Cambridge either.

No trains expected to run between London and Peterborough for the rest of the today with disruption also expected tomorrow morning. Services to cambridge have now resumed but heavily delayed.

I was caught up in this earlier, I arrived at King's Cross to find nothing running, I made a quick decision to pop to Moorgate where thankfully the inner-suburban services were still running. Not much social distancing was possible on the train I travelled on but it was good to see the new platform 5 at Stevenage getting a proper workout with large passenger numbers.

Anyone else caught up in the disruption or knows what's going on?

Was absolute chaos at King’s Cross earlier when I passed through at roughly 17:30. Every train on the board showing “cancelled”, let’s hope they fix it soon, this could be a very expensive one indeed :|

The only train to leave Kings Cross since 1400 Edinburgh (3 hours plus late currently) has been the 1830 which has gone via Cambridge. Only the 0755 from Inverness and 1230 from Edinburgh got diverted via Cambridge

Potentially a route knowledge issue as much as a traction issue.

Not much point wiring diversions if signing them is few and far between...

Always seems quite troublesome on this stretch indeed.

I see Thameslink have been trying to just run a service between Peterborough and St Neots.

I don't want to go OT but if Cambridge- Peterborough was sparked up it would be valuable for incidents like this and part of F2N/West Midlands for freight too.

The OHLE has always had problems on this section of the ECML

As I said upthread, it should be considered a higher priority for conversion to portals then.

Anyone know why Hitchin - Cambridge was also shut for a long period? Is it on the same electrical section when the current tripped?

The emergency isolation took out a large section; took until 1745 for the OHL gang to shorten the isolation due to access issues via a farmers field. Once the isolation was shortened, the route off towards Cambridge was available.

I made it as far as Biggleswade. Never gotten off there in my life. Waited on the train for over an hour, decided to take a walk, found a lovely cafe, relaxed for an hour, returned to the station to find chaos unfolding and was offered either a replacement bus to King’s Cross or a taxi home to Peterborough. Gleefully accepted the taxi home, happily called work and said it ain’t happening today and got home quite rapidly. All in all a decent day! I guess I was one of the lucky ones.

Is that Biggleswade MPTSC or one of the adjacent TSCs which has been damaged ?
It looks like one of the across-track feeder jumpers for Biggleswade MPTSC, but a quick check on a cab ride video shows that the feeder for the structure in question was for the insulated overlap on the Down Fast - the Up Fast got dewired, so no need to replace the jumper.

I arrived at Finsbury Park about 3pm to find nothing but the ex-Moorgates heading north. Ours went as far as Watton-on-Stone before emptying out as P5 at Stevenage was occupied by a train presumably driverless

That is a spot of less than terrible news then.

On the subject of wires I was surprised when there didn't seem to be any mention of speed restrictions during the record breaking temperatures in August,

Quite surprising as higher temperatures would lead to sagging wires

Not when the auto-tensioning is working correctly...

...the Mk.3 ECML catenary, for its significant number of failings (and failures) isn't like the old GEML compound catenary with its fixed termination, (semi) fixed tension system. It can cope with a reasonable window of temperatures as long as the tail wire pulleys and counter-weights aren't seized solid...
