There may be "some impact on punctuality" as a new rail timetable is introduced on Sunday, the Rail Delivery Group have warned.
It will be the first national timetable change since the chaotic introduction of new schedules in May, for which transport secretary Chris Grayling was heavily criticised.
The RDG has decided to reduce the scale of the alterations in the winter timetable, which will delay the launch of some new services.

Among the improvements being introduced are 200 additional weekday services on Thameslink and Great Northern routes, and a reduced journey time between Edinburgh Waverley and Glasgow Queen Street.
RDG regional director, Robert Nisbet, said: "We know that people in some areas might be concerned about another timetable change, but - as the Glaister Review acknowledges - the rail industry has worked together to start learning the lessons from May.
"As with the introduction of any new timetable, there may be some pockets of disruption as people get used to new journeys and train times, so we advise people to check before travelling next week."
'Passengers need to see that lessons have been learned'
Anthony Smith, the chief executive of watchdog Transport Focus, said he hoped "lessons had been learned".
"This time around passengers expect the rail industry to drive a smooth set of timetable improvements," he said.
"Passengers paid a hefty price for the catalogue of over-optimism, missed deadlines and blurred accountability that led to a summer of timetable crisis and ensuing chaos. To regain their trust, passengers need to see that lessons have been learned."
Rail timetables are changed twice a year, in May and December.
