So we knew there will be the ASLEF Train Drivers strike on the 15th of September and the TSSA and Network Rail strike from noon on the 26th until noon on the 27th, but now it gets even worse.
40,000 RMT workers at 14 train companies and also Network Rail are walking out on two days - the first is the 15th of September to coincide with 9,000 ASLEF Drivers (the biggest yet) strike at the 12 companies, - the second is two days later on the 17th of September.
This is a big one.
That means that on the 15th virtually the entire country will shut down.
A decent condensation of these strikes is at https://www.timeout.com/uk/news/everything-you-need-to-know-about-september-rail-strikes-082522
Feel free to ask about your situation if it isn't covered in that article. Most questions will be, and there are some which can't be answered.
UPDATE
A National Rail Enquiries link to all affected railways and their strike page is at https://www.nationalrail.co.uk/service_disruptions/304915.aspx
