Drivers of three more train companies will go on strike later this month, making disruptions to already-forecast railways worse.
Drivers working for Hull Trains, Greater Anglia and Croydon Tramlink have all voted to take industrial action in separate disputes over pay, union Aslef has announced.
It comes as the RMT alliance says up to 50,000 members of its network on Network Rail, 13 train operators and London Underground will launch on 3 days in June – Biggest rail industry action boom since 1989.
Taking place over three days, the strike action threatens to “shut down the system”.
Negotiations between Network Rail and the union are expected to take place over the next few days, with the former laying out contingency plans to try and ease disruptions to services.
Fewer than one-fifth of trains are likely to run and only between 7am and 7pm, perhaps only on the main lines.
