Feeling sure that I've seen long ago that the idea will be it needs 9 diagrams- as does the full 4tph Stansted service.

Class 37. The errant set should be in Norwich by now.
If I used a wheelchair I don’t think I’d want to try bridging that gap!
It's 10 diagrams, there's a half hour turnaround at each end.

But you see my point. In fact that's even worse. They're barely going to be able to do any maintenance during weekdays. And going by their track record they'll need all the depot time they can get

Well then it'll be 720's subbing in for Norwich/Stanex depending on which subfleet has the lack of availability. It does seem a little ambitious given the required service on both sides, maybe theres a big shake up coming with the timetable, or theyre planning on squeezing some extra time out of the turnarounds, there are likely efficiencies that can be made that will no doubt be part of the wider new fleet plans

The plan is 9 diagrams. Tightening of timings which the 745s enable will allow a diagram to be saved, or that's the plan. So 9 from 10 on both fleets.
The original diagram plan was based on both WA and GE timetable recast. Was originally due May 2020. 
WA now not expected until Dec 2021 earliest, to coincide with East Coast recast as that affects KX/Thameslink - Cambridge. GE no one knows.

Indeed. On paper each unit sees Crown Point every 9 days for about 6 hours max for the 745/1s, 30 hours if you replace it with the spare, assuming it is available. Ambitious it is, but no doubt there are penalty payments if Stadler can’t meet the required availability. Not that is much comfort to a first class season ticket holder on the Norwich line, if many still exist, who will likely see standard class only trains replacing the 745/0 on occasions.
Compared to today that’s a saving of one diagram on the Norwich’s. The Stansted service is the same requirement, where it is much harder to tighten the timings partly due to the single track through Stansted tunnel. Commercially it is desirable to always have a train ready to board at each end, especially at Liverpool St where you don’t want lots of suitcases clogging the concourse.

That document looks laughably inaccurate now!

Some might say it looked laughably inaccurate back then too

What, the couplers unintentionally parted in service? I didn't know that was common on 379s.again

He means they split up a pair of 379s to run two diagrams to replace the 745 one and keep running the original 379 diagram. Unless you're joking? in which case its customary to use an emoji or emoticon.
The electrostars had an issue fairly recently with splitting in service, can't remember when but it was fairly recently.

I'm aware of that custom.
I simply misunderstood the spirit of the post: I thought what he meant was that the 745 had been subbed with a pair of 379s, which were stuck at Sawbridgeworth because they had parted in service and wouldn't couple again.

He means nothing of the sort. The 379s parted in service. RAIB investigations ongoing.

So I am correct in my original interpretation that this is why the train was stuck at Sawbridgeworth? Because two Electrostars parted in service?
Sorry, I'm a little confused at the moment with everybody seemingly having a different idea of what's happening
That's how I read @dk1 post and he has just confirmed.

AH. Sorry there. Completely misunderstood all that. This being the Class 745 thread completely threw me off.
Perhaps someone could set up a thread for StanEx discucion if 745/1 operations start becoming affected a lot by that.

Not necessary. Someone posted an RTT link showing a StanEx service being disrupted and asked if it was a 745 at fault, and this would be a fair thread to do that in. It was not, and the real reason was then cited.

A pair of 745s on Stansted diagrams today - 106 and 107
Looks like they ironed out the initial issues then.
Strange to be on a Stansted service holding a steady speed.
Is it my imagination or is the Roydon LC slow to clear?

All the crossings down there can be, as the crossing keeper controls 4 others as well - if there’s an issue at any one of them (someone slow to clear off the crossing) it will likely delay another closure sequence.
On the Stansted Express a lot of it boils down to not going at linespeed constantly. Departing Tottenham on the down road there's no point in getting up to 85 to just catch up the Hertford eg along the valley, also gives the Signaller a better chance of sorting out the crossings.

Okay so just quickly for us none London folk, can someone give a summary of how the roll out is going and whether 379s or 321s/755s still replace 745s in service on both routes?
