That's a fair point - I only know about it because of the discussions on here, and even then until this thread I assumed it would just be the Ely terminators, as it was (I think) in 2021.
Is that likely to be complicated by the services that are only 12-cars on Tuesday through Thursday? Seems from RTT that they are set to continue in the new timetable.
I can't say I'm remotely looking forward to seeing the possibility of 700s on my commute again, even though it is (comparatively) very short.
Okay the good news for you is that there’s only a couple of 700 workings which reach Kings Lynn, and as I suggested they avoid core commuter services:
1T94 0602 King’s Cross to Kings Lynn (this is a new service and replaces what was a Thameslink King’s Cross to Cambridge service as far as Cambridge, which also means a reduction from 700/1 to 700/0 - though not really a problem at that time of morning!).
1T38 1442 King’s Cross to Kings Lynn
1T15 0812 Kings Lynn to King’s Cross
1T49 1642 Kings Lynn to King’s Cross
The bad news is that 700/0s will appear on Ely services five times on weekdays.
It’s a similar picture on Saturdays, though less to Kings Lynn and more to Ely.
The interesting question is that if this arrangement is indeed intended to be temporary, then these handful of disgrams will require to be replaced by 8-10 387s or equivalent. Add in another 5-7 to replace what’s going to be 700 working on the peak Peterborough services, and we’re not far short of the low end of the tender. But what are around 8x displaced 700 (mainly 700/0) going to do?
