RAILWAY services between Darwen and Bolton have been cancelled.
A Northern spokesman said this due to a points failure at Bolton which has lead to them becoming blocked.
The spokesman said: "Train services running through these stations may be cancelled or delayed by up to 15 minutes.
"Disruption is expected until the end of the day.
"Our advice to our customers is due to a points failure at Bolton station train services are unable to use platform one and platform two, therefore services between Darwen and Bolton in both directions may be subject to delay and short notice alterations and cancellations until end of service today.
"If you've been delayed by 15 minutes or more, hold on to your tickets and claim compensation by visiting northernrailway.co.uk/delayrepay."
