Football fans who may be considering travelling to Wembley by train for Monday’s play-off final are being urged to make alternative arrangements because of strike action.
Members of the RMT union who work as signallers and maintenance staff for Network Rail are due to stage the walkout on Monday and Tuesday in a dispute over pay.
Talks are continuing in a bid to halt the action, which would be the first national rail strike for 20 years if it goes ahead.
But Great Northern, the company which operates most passenger services from West Norfolk to London, has urged passengers not to travel at all during the strike period.
It says that, if the action does go ahead, they will only be able to operate an extremely limited service from around 7.30am until mid-afternoon, at best.
And officials have also warned of the potential for major disruption next Wednesday as well.
A statement on the company’s website continued: “We cannot guarantee that we will be able to run or maintain this level of service and we advise you not to travel. Those services that do run will be extremely busy.
“The number of trains we are permitted to operate by Network Rail will be very limited indeed. We cannot therefore guarantee to get you to your destination.”
Passengers who have to travel are being advised to do so either before or after the strike, on Sunday or Wednesday.
They are also being advised to keep checking for updates in case the situation changes over the coming days. Refunds can also be obtained for tickets which have already been purchased.
