More needs to be done to improve passenger journeys on South West Trains, after satisfaction dropped.

Research showed passenger satisfaction stood at 80 per cent, having dropped 1 per cent year on year.

Tim Shoveller, chief executive for the South West Trains-Network Rail Alliance, said: "Our current level of performance is not where it needs to be and more work needs to be done to deliver the train service our customers deserve.

“There is no quick of easy fix to improve reliability, boost capacity and catch up on years of under investment at the same time as running the UK's busiest railway and carrying over half a million people a day.

“But we are determined to work with the government and do everything we can to deliver a better railway for our customers.”
