The National Rail Enquiries website has crashed on the first morning of UK train strikes. Several parts of the country have been left without any rail services at all, while others have been heavily disrupted and people are advised not to travel unless absolutely necessary.
The National Rail website is used by commuters and less frequent travellers alike to view up-to-date train times, platform departures, plan journeys and book tickets. But anyone attempting to use the site this morning is greeted with an 'Error 552' message. The National Rail app, however, still appears to be working.
A message in the app when searching for journeys says: "The RMT union has announced strike action on Tuesday June 21, Thursday June 23 and Saturday June 25. Customers are strongly advised to only travel if absolutely necessary on strike days as there will be significantly reduced service, some routes will not be served. Please plan ahead and check nationalrail.co.uk/industrialaction fir updates."
