All rail lines are currently blocked between Doncaster and Scunthorpe due to problems with a river bridge.
As a result of the problem at Keadby canal bridge, disruption is expected to continue until at least 1.15pm, with rail passengers advised to expect delays and cancellations.
Further information on the problem causing the delays is not yet known.
A spokesman for TransPennine Express said road transport is currently being sourced.
