Yes. If you can remove the change entirely (assuming it isn't too far to drive in one go) that would near enough remove the issue.
Completely agree of some of the Cross-Manchester services. Only 2 sets of traincrew sign the full route!
The Blackpool North-Hazel Grove services for example only Manchester Victoria & Buxton sign the full route. Manchester Piccadilly drivers sign as far as Preston.
The Southport-Alderley Edge and Liverpool-Crewe usually require a full crew change at Oxford Road. As neither crew sign the other half of the route (Liverpool, Wigan and Manchester Vic can go to the Airport).
Buxton guards actually sign Wigan Wallgate-Alderley Edge so they could work throughout, don’t think the drivers sign Wallgate though!
In terms of relief it would make much more sense for relief on the Liverpool-Crewe services to happen at Manchester Airport but you would lose any productivity as the departure back to Liverpool is too close there wouldn’t be time so they’d end up sitting at the Airport for an hour, like most do at Oxford Road anyway.
Unfortunately most of the dockets invite delays when there is disruption.
There’s a Lime St driver one which is:
Lime St-Oxford Road (via Chat Moss)
Oxford Road-Lime St (via CLC)
Lime St-Oxford Road (via Chat Moss)
PNB
Oxford Road-Lime St (via CLC)
Lime St-Oxford Road (via CLC)
Pass back.
It’s asking for trouble!
