Northern cancels about 80 Sunday rail services
Northern has cancelled about 80 rail services on Sunday and expects to abandon more, as some train staff have "made themselves unavailable".
The firm apologised for the disruption, which will mainly affect Liverpool, Lancashire and Greater Manchester.
Staff contracts mean employees do not have to work on Sundays if they provide seven days' notice.
It follows similar disruption across the network on the day of the World Cup final on 15 July.
Chaos on the Northern network, caused by a new timetable's introduction in May, has been the subject of much passenger misery this summer.
Services resumed earlier this week after the operator ended up cancelling 165 daily train services until the end of July.

Speaking about the Sunday cancellations, a Northern spokesman said: "Unfortunately we have so far had to cancel around 80 services across our network and it is likely more will be cancelled as we continue to plan our services.
"On each route, customers will either have other rail options via Northern and other operators or will have the provision of rail replacement transport."
Commuters have been advised to check the operator's website or National for updates.
