Rail operator Northern is reminding passengers that new train timetables will be in operation from Sunday (12 December).
Rail passengers are being advised to check before they travel as there may be changes to their usual journeys and departure times.
Services between Hadfield-Glossop and Manchester Piccadilly, the Hope Valley line between Manchester and Sheffield, and Manchester Piccadilly and Buxton will be affected.
The timetables, which are set to run until 14 May 2022, can be accessed here: https://www.northernrailway.co.uk/travel/timetables
Northern have also been promoting the timetable changes via social media and web channels, as well as posters and announcements at stations and on-board services.
Passengers are being told it is more important to check journey details before travelling and even more so over the festive period, with planned changes and amendments across the rail network.
Northern is also still being affected by the ongoing impact of coronavirus, with passengers also being advised that there may be 'some staffing and resource issues' therefore services may be subject to 'short term alterations and amendments'.
Rail users are also reminded that government rules state that face coverings must be worn while travelling on trains and at stations, unless exempt.
A Northern spokesperson said: "Our rail timetable changes on Sunday 12 December and our message to customers is very clear, please check the details of your journey before you travel as there may be amendments and alterations.
"We have worked extremely hard to plan the timetable and where possible we will be providing more services across the network.
"The festive period is always extremely busy and there may be reduced schedules and planned engineering which could affect some journeys. coronavirus also continues to mean operational challenges and we recommend using nationalrail.co.uk and our digital channels for the most up to date journey information."
