Subway conductors walked off the job in protest to the firing of the head of a local union unit , Per Johansson, by Connex - which run’s the city’s subways.
Connex says it dismissed Johansson because he had acted ”disloyally” towards the company and was offensive towards his co-workers. But his supporters say he was sacked for criticising Connex’s safety work.
Worst hit Thursday morning were stations like Slussen and Gullmarsplan, where buses from the suburbs connect with the underground. Replacement buses were brought in to ferry passengers from station to station but there were serious delays.
The disruption led to a surge in business for Stockholm’s taxi companies. They say it was hard to cope with rush hour demand.
Stockholm’s subways are now back up and running.
Connex, which operates worldwide, lost its UK rail franchise in 2003. Reasons for this included its failure to meet a detailed action programme of improvements to its service.
