Passengers using Birmingham New Street Station are being reminded to check their platforms when a £7.5million repair project begins.
Maintenance work will be carried out on the 1960s concrete roof from 2nd April.
Network Rail said the project was expected to take around eight months to complete.
It will begin with the closure of platforms five and six, with others closed in pairs over the course of the works.
Denise Wetton, Network Rail’s central route director, said: “Our major work to renew the roof above Birmingham New Street’s platforms is a vital part of a wider programme to keep the iconic station running reliably and looking its best for passengers.
“The temporary platform closures will mean changes to train services and we’re asking passengers to plan ahead and check with their train operator to see how their journey will be affected. I’d like to thank station users in advance for their patience while this work takes place.”
In addition to changes to platforms and train departure timings at Birmingham New Street, there will also be changes to weekday CrossCountry services between Nottingham and Birmingham New Street.
John Robson, regional director for East Midlands and East Anglia at CrossCountry, said: “There will be significant changes to train services between Nottingham and Birmingham via Derby, Burton-on-Trent and Tamworth while this important upgrade work takes place.
“We urge our customers to check our website for full details before they travel and thank them for their patience while these important improvements take place.”
