The pledge from rail union Aslef came as up to 100,000 train passengers faced chaos during a second walk out by drivers over pay.

Aslef went ahead with the strike on Tuesday and Wednesday, leading to the cancellation of most First North Western services.

It accused the company of attaching "unacceptable proposals" to a 19% pay-rise offer.

Arbitration failed

The union claims First North Western wants drivers to take on responsibilities such as picking up litter at stations.

However, the operator insists the union reneged on an agreement previously reached to give drivers the pay increase over three years.

The action, which was set to continue on Wednesday, came after the first walkout on 13 and 14 August. The next strike is planned for 10 and 11 September.

Negotiations organised by the conciliation service Acas broke down last week.

Planned strike

However, an Aslef spokesman said the union was willing to reconvene talks.

He said: "We are willing to get back around the table but no meeting has been scheduled.

"It is almost inevitable Wednesday's action will go ahead but the outcome of any talks could of course have an effect on the planned 48-hour strike next month."

The affected region includes stretches from Carlisle to Buxton and also includes North Wales.

First North Western was unable to comment but managing director Vernon Barker has previously said: "I remain available at all times to talk to Aslef".
