DLR staff could earn up to an extra �2,500 during the summer Olympic and Paralympic Games when the driver-less train service is expected to ferry an extra 2.28m summer visitors around London’s sports venues, mainly to Stratford.

Serco Docklands management said they were pleased their staff’s RMT union Executive Council have agreed “a fair package of recognition and incentives for employees.”

Apart for the volume of additional passengers the service will run additional trains, an extended service and staff 25 instead of four stations.

The agreement affects around 550 employees and it helps meet the 45,000 additional hours needed to run the enhanced service.

It guarantees staff working during the nine-week Games period a minimum of five hours overtime per week and a weekly �100 bonus.

The Rail, Maritime and Transport Union said the deal has “raised the bar”.

It has already won Olympics payments of �500 for Network Rail staff and �600 for London Overground staff while rejecting an offer of a �100 bonus for Tube workers.
