(Bloomberg) -- Trains on London’s £20 billion ($24 billion) rail line will mostly come to a halt on Thursday as workers walk out over pay and pensions.

No trains will run between Paddington and Abbey Wood, affecting stations that serve major financial hubs such as Canary Wharf and Liverpool Street. This central part of the line carries more than 200,000 daily users. 

Limited services will run on sections of the line further to the east and west of the capital. The Elizabeth Line finally opened in 2022 following years of delays.

The action by staff represented by the RMT, TSSA and Prospect unions is over pay as the groups rejected a proposed 4% raise. The unions claim other rail and Underground workers in London have been given more.

“Our members have the power to bring the Elizabeth Line to a standstill and that is exactly what will happen as a result of this strike and the lack of a serious offer from TfL,” said Mel Taylor, a TSSA organizer.

The industrial action is a blow to a line which has been seen as a success after it carried more than 11 million riders in its first three months. RMT general secretary Mick Lynch said that workers should be rewarded for contributing to the success of the line.

The strike will also affect commutes on Friday morning, and a work to rule is in place for the following six weeks, risking further disruption. Bus services in south and west London will also be affected due to a separate union dispute with Abellio.
