East Midlands Trains services are now running between Nottinghamshire and Derbyshire after disruption this morning.
The service has been restored from Nottingham and Mansfield/Langley Mill and departures are now running as scheduled.
The services were disrupted earlier after a signalling fault at Radford Junction.
Replacement bus services were arranged between Nottinghamshire and Derbyshire whilst a team from Network Rail investigated and fixed the problem.
A spokesman for East Midlands Trains said: “We are sorry for the delay to your journey today.”
