If a lot of services don't run for whatever reason safety will be a concern. Maybe XC stopping more services at Congleton would reduce safety concerns as passengers wouldn't all have to crowd on to the same peak time service which usually stops there?
No-one seems concerned about Arriva buses being full to maximum capacity due to carrying rail passengers as well.
I know this is an old post but I've had some 'interesting' conversations with northern via Twitter DMs regarding extra XC stops at Congleton on strike days.
There's the same process every time;
1. Not our problem, ask CrossCountry (In a polite and understanding way to be fair)
*Upon asking XC they say; 'Not our problem, northern need to ask us.' (Which I believe is correct)
2. We'll pass this to our train planning team. (I thank them and wait)
3. After no response from them I chase it up and get; 'This has not been possible'
when i ask why I get 'Requests for extra calls have been rejected by the planning team.'
Then the strike day comes around and I see many ATW and EM making additional calls.
Most frustrating is ATW making additional calls at Sandbach - Which isn't served by ATW at all...
This happens every time - I was at Congleton station for 10 minutes to pick up some tickets last strike day and I had to turn away 4 groups of people because they had no idea (no info - no staff) - Ridiculous!
