A damaged power cable in Wembley has caused long delays to rail services across London and the UK.
Trains to and from Euston were suspended on this morning and commuters were forced to take alternative routes to reach their destinations.
Virgin Trains and London Midland services were disrupted after an overhead power line on the West Coast Mainline was severely damaged at 9pm yesterday.
A Network Rail spokeperson said: "Trains are expected to be running through the affected area by 10am this morning. Virgin will run two trains per hour from Euston to Birmingham and Manchester and one per hour to Chester, Liverpool and Glasgow, this is a reduced service. London Midland will also run a modified service.
"Network Rail specialists will work throughout the day and night to repair the infrastructure with the aim of a full service tomorrow morning.
"Passengers are advised to check with train operators or national rail enquiries before travelling. Network Rail apologises to anyone whose journeys have been disrupted."
Richard Lakin from London Midland, which runs trains to Euston through Harrow and Wealdstone and Wembley Central, said: "We would like to apologise to passengers for any inconvenience and we are asking customers to seek alternative modes of transport."
