Ongoing works to improve Leeds station mean trains will be severly disrupted over a weekend in October.
Network Rail is advising passengers to check before they travel on the weekend of October 26-27 as work continues on the construction of platform zero.
-> This is what is being built at Leeds station and when construction will finish
Some services will not operate and others will run a reduced timetable.
On Sunday morning - the day of the Leeds Abbey Dash race - there will be no trains in or out of Leeds station, with rail replacement buses in place across all routes.
Runners of the 10k race between the city centre and Kirkstall Abbey, and those who will be supporting them, are being urged to allow extra time for their journeys.
Platform zero, set to open in 2021, is being constructed on land currently occupied by the outdoor long-stay car park.
Network Rail say it will provide more space for trains at Leeds station, resulting in improved punctuality.
A redesigned and simpler track layout of platforms one to six and improvements to the signalling across the entire station are also taking place.
Chris Montgomery, Major Programme Director for Network Rail, said: “When platform zero comes into use in 2021, it will benefit not only those passengers travelling to and from Leeds, but services across the region, as it takes the pressure off the station and reduces the impact of knock on delays.
"The work we are doing at Leeds will have an impact on services throughout the weekend of 26/27 October and we would like to apologise for any disruption or inconvenience this may cause.
"We wish to thank passengers for their patience whilst this work is carried out.”
-> Calls to reopen Leeds' other city centre train station
A spokesperson on behalf of train operators using Leeds station said: “We would like to take this opportunity to let passengers know that there will be changes to services as Network Rail continues work to improve Leeds station.
“We would advise anyone planning on travelling to, from or through Leeds on Saturday, 26 and Sunday, 27 October to check their journey in advance.
"We continue to work with Network Rail to keep disruption to a minimum and we would like to thank all those impacted for their patience."
