East Midlands Train services north of Chesterfield in Derbyshire are running again from today, after a landslip closed two sections of track last month.
Extremely wet weather led to a hillside becoming unstable between Chesterfield & Sheffield, putting two tracks at risk on February 18.
Since then a revised service has been in operation after one of the two tracks near Unstone was closed
Initial estimates indicated that services would be disrupted for four to six weeks. However work on site progressed better than expected, and the lines reopened this morning.
Network Rail thanked affected passengers for their patience, saying:
The work completed so far has prioritised making the track safe so that trains can run but work to fully stabilise the hillside will continue for several months yet. Trains will run at a slightly reduced speed past the worksite but this will not significantly affect journey times.
