I was on the 0847 Crewe to Carlisle (
https://www.realtimetrains.co.uk/service/gb-nr:S22935/2026-01-03/detailed#allox_id=0) which was delayed 40 mins because they tried to join the 2 sets (separately off the carriage shed) in the platform and then found that they couldn't get the front set doors to open. Checked on the approach to pfm 4 at Warrington and then overtime for the same reason, 19 late from Wigan. It was further delayed at Blackburn but after that it went fine, losing a couple of minutes to Armathwaite but regaining 5 before Carlisle. Pity none of the staff realised that the front set doors hadn't released, lots of passengers banging on windows to attract platform staff attention, passcom/toilet alarms pulled etc. One chap watched his Newcastle connection set off...
Finally after exactly 10 mins we were allowed out through a staff door at the rear of the unit - and I was pretty well the closest to it. Both units were quite well filled by my reckoning, standard virtually full when I walked through to the shop.
The 1423 return to Wigan had the rear (door fault) set locked out, first class was pretty well full up (2 blokes went back to standard to find a seat facing forwards) and I guess standard was the same. It only lost 2 mins to Ribblehead but was checked at Settle Jn by a late-running Morecambe to Leeds, then again at Blackburn, arriving into Wigan 5 late.
Apart from the morning shambles at Crewe and the fact that the whole set was like an icebox until a member of the crew announced, after Wigan I think, that they had noticed it and reset the thermostat I didn't find the train's actual performance to be a frustration!
