South West Trains said that fare changes were determined largely by government policy and that they were working hard with the rest of the rail industry to make the system more cost-efficient.
They also pointed out that they had experienced an increase in their overall satisfaction rating.
Tim Shoveller, Managing Director of the South West Trains-Network Rail Alliance, said:
"It’s good news to see that satisfaction with our services has improved and we are determined to continue working hard to improve these scores even further....These results, which provide independent views from our passengers, really do help us to focus on the areas of improvement needed and we will continue to target these areas to meet the needs of our passengers.”
