Commuters are facing major problems on the trains this morning, with a number of trains cancelled.
A signal problem in the Sellafield area means Northern Rail has been forced to cancel all services between Millom and Whitehaven this morning.
It is currently trying to arrange a bus replacement service, but has not yet been able to do so.
Work is underway to fix the signalling fault, but services are not expected to resume until 8.30am at the earliest.
