LONDON Underground maintenance workers began a 48-hour strike at 7pm last night, after last-ditch legal action by employer Tube Lines failed.
A High Court judge denied Tube Lines an injunction to stop the strike, despite arguments that the strike ballot was invalid.
“We urge the RMT to pull back from taking this needless action which would unnecessarily inconvenience the travelling public,” said Tube Lines acting chief executive Andrew Cleaves.
Transport for London has insisted that train services will not be affected by the walkout on the Northern, Victoria and Piccadilly lines.
However Bob Crow, general secretary of rail union RMT, called the ruling a “massive victory” and predicted major disruption across the London Underground network.
Another strike against proposed job changes is set for 14 to 16 July.
