All train lines between Carlisle and Lockerbie are blocked due to a fallen tree.

Rail passengers are being advised not to attempt to travel between England and Scotland.

All lines are affected on the West Coast Main Line, between Carlisle and Lockerbie, due to a tree falling on overhead line equipment in Floriston, just south of Gretna.

Network Rail, which manages Britain's rail infrastructure, is attempting to repair the damage.

There is reported chaos at Carlisle train station, as replacement buses and taxis attempt to ferry passengers over the border - many of whom were stuck for hours on trains or in stations.

Virgin Trains said it is not possible for passengers to use the East Coast Main Line as an alternative route due to disruption caused by a person being hit by a train.

Passengers for East Coast services are being advised to check before they travel.

A spokesman for the operator said: "The closure of our route to Scotland is causing significant disruption and we want to apologise to all our customers affected by this.

"We're doing our best to help people complete their journeys but would advise anyone who has not set off on their journey to either wait until the disruption has cleared, travel tomorrow or get a refund."

Virgin Trains, Transpennine Express and Scotrail services are all affected.

Meanwhile, the train cancellations have led to heavy congestion on the A7 southbound at Georgian Way and Stanwix Bank heading into the city centre and towards the rail station.
