NORTHERN'S latest 'flash sale' is on, and train tickets for £1 are now up for grabs.

Passengers are being encouraged to use a new ‘Low Fare Finder’ tool on the Northern website to check the £1 ‘flash sale’ tickets available from their local station.

Northern launched its latest sale yesterday, Wednesday, and it runs until tomorrow, Friday, January 5.

Five million £1 tickets went on sale across the north of England yesterday, and are up for grabs until 4pm on Friday.

'Flash sale’ tickets are valid for travel between Wednesday, January 10 and Friday, March 1 and must be booked at least seven days in advance of travel.

The 'Low Fare Finder' can be found here:

Mark Powles, commercial and customer director at Northern, said: “The ‘Low Fare Finder’ is a great new tool to help people find the cheapest fares – fast.

“And the ‘flash sale’ is a great opportunity to put it to the test – with five million tickets from just £1 available across the network up for grabs.

“As always, customers should book early to avoid disappointment.

"Once they’re gone, they’re gone.”
