Train companies have started cancelling services over the Bank Holiday due to a planned strike by thousands of Network Rail workers - despite peace talks continuing.
West Coast main line operator Virgin Trains has scrapped all services on Monday and Tuesday and warned it would only be able to run a very limited number of trains on its East Coast line over the two days.
An outline of how the strike will affect all train companies is expected to be revealed later today, but passengers were warned to expect severe disruption if the 24 walkout goes ahead from 5pm on Monday.
CrossCountry Trains, Chiltern Railways, Arriva Trains Wales, First Great Western and ScotRail were among those giving passengers an early idea of the travel chaos they can expect.
Passengers were being advised not to travel unless "absolutely necessary", with widespread cancellations expected, leading to packed trains.
