Edinburgh railway workers will go ahead with a planned strike on New Years Eve, causing possible travel disruptions throughout the day.
Workers at Edinburgh Waverley and catering staff are caught up in two separate disputes, as Rail, Maritime and Transport Union (RMT) have confirmed the 24-hour walk out.
The dispute on Cross Country involves train managers and senior conductors in a row over the role of guards.

The action at Edinburgh Waverley, by staff employed by Gate Gourmet, is part of a long-running dispute over allegations of bullying.
RMT General Secretary Mick Lynch said: "The disruption to services from the New Year's Eve strike action is wholly down to these greedy private companies on our railways seeking to squeeze out every penny they can by hammering down on safety, jobs and workplace dignity.
"Our members at Cross Country and Gate Gourmet are standing up for all rail workers as we expect a torrent of attacks on jobs, pay, safety, pensions and working conditions in 2022. We are ready for a New Year of campaigning and action on all fronts."
Cross Country said it expected disruption to its services, adding it would only be able to run a "very limited" timetable.
A statement said: "We are advising customers to alter their plans where possible and to avoid travel on December 31."
