Rail passengers are facing severe disruption on the line between Swinton and Doncaster due to vandalism involving a fire near the railway at Conisbrough.
The fire took place last night and caused severe damage to signalling equipment and cabling.
The line between Swinton and Doncaster will be closed for up to 24 hours and buses will replace trains in both directions to allow Network Rail to carry out the necessary repairs to the damage.
Customers are advised to change at Meadowhall or Doncaster for onward connections.
Northern are continuing to work closely with their colleagues at Network Rail to keep the disruption down to a minimum and say they're very sorry for the delay and inconvenience this will cause to your journey.
