A safety inspection of the track between Oxenholme Lake District and Lancaster means that trains have to run at a reduced speed on some lines. Trains running between these stations may be delayed by up to 55 minutes.
Disruption is expected until 10:45.
Network Rail staff are on site to fix the issue.
