UPDATE 2.50pm: It's OK, everyone stand down. Both unions have called off the strike action after reaching agreement with Network Rail.
ORIGINAL STORY: Weren't planning to do anything rail-related over the bank holiday were you? Or use the trains to get to work on Tuesday? You were? Then you may need to revise your plans, because Network Rail staff are going on strike.
Network Rail is the company that maintains the track, signals and power supply, so for once you can't blame this on your local train operator. The strike is currently slated to start at 5pm on Monday and run for 24 hours, with no overtime throughout Monday and Tuesday. Talks are ongoing though and there's always a chance it will be called off. The dispute is over a four year pay offer which the TSSA union says would mean its members falling behind the cost of living.
Services affected in London
Follow the links for more information on the train operator's website; more detail will be available on Saturday and we'll update this article then. One common theme that comes across though: these companies really really don't want you to travel.
