Thanks for pointing this out Natasha - first I've heard of it. I travel by train every day at the moment so I will let you know ASAP what's happening in my part of the country. Fingers and toes crossed!!! This will also affect people attending the YMO concert on Sunday - couldn't they wait til the following weekend to protest!!!
Update: I've just had a look on the National Rail Enquiries website and at the moment there are no planned strikes for 14th except on East Midlands Trains. Of course this could change during the week. Also people travelling by train please check if your route is going to be affected by engineering works, and those of us using the underground please check the Transport for London website for line and station closures. For example I hope to use the Victoria line next weekend, but this weekend it is completely closed down. SO double check before you travel!
