Trains running between Lincoln and Sheffield this week will face delays due to engineering works on the route.
Engineers are working on signalling between Worksop and Lincoln, which is causing disruption to Northern Rail’s normal services.
Northern Rail believe that trains along the route will be delayed in the area by up to 20 minutes.
This is due to replacement buses used between Worksop and Retford for passengers.
In a statement, Norther Rail said: “It is vital the work is completed to provide a safe, efficient and reliable train service for the area.
“We would like to apologise to all our customers affected by this and thank them for their patience.”
It is presently unknown how long the signalling work will take to complete.
