One thousand extra train services a week are being put on by Great Northern, Southern and Thameslink from May 16 as restrictions ease across the UK.
Steve White, chief operating officer of parent operator Govia Thameslink Railway, said: “As lockdown restrictions are eased, we are reinstating services for our returning customers. These additional trains will help provide more space on board by adding more capacity on our busier routes at the most popular times. They will also provide more journey choices for customers at quieter times.
“Social distancing will become more challenging as more people start to travel again, so we’d advise everyone to use online journey planners which will highlight the busiest services to help you plan an alternative time or route if you can.
“Our team are really looking forward to welcoming people back to the railway.
“As customers return, and the impact of Covid on our resources allows, we will continue to review and increase our services based on feedback from our passengers, hospitals, vaccination centres, schools and businesses.
“This will ensure that we continue to support our customers and our communities as we did during the height of the pandemic.”
Passengers returning to rail should wear face coverings unless exempt and maintain social distance.
Gatwick Express, however, remains suspended.
