People travelling by rail this month are being warned to expect some disruption on the Bradford, Brighouse and Mirfield routes to London, especially at weekends.

Network Rail is carrying out engineering work. It might only involve slightly re-timed services but in some cases could involve Grand Central passengers changing trains at Peterborough or Doncaster, with longer than normal journey times.

Details are at grandcentral rail.com/planned-alterations. The disruption will also affect passengers who use other rail companies.
