Poll: Are you happy with the service provided by rail companies?
Rail passenger satisfaction in Britain has risen for the first time since 2012, according to new research.
A Transport Focus survey of more than 28,000 passengers found an increase in overall satisfaction to 83% in autumn 2015 - up from 81% year on year.
The operators with the three lowest ratings are all in the South East, where long-running improvement work at London Bridge station is causing disruption to services.
Thameslink had the lowest proportion of satisfied passengers at 73%, followed by Southeastern (75%) and Southern (78%).
The highest scores were achieved by First Hull Trains (97%), Heathrow Express (95%), Grand Central (93%) and Merseyrail (93%).
Nationally the overall score for commuter satisfaction was 76% - up from 73% on the previous year.
The proportion of passengers satisfied with the value for money of the ticket nationally was 48% - up from 46% in autumn 2014 - but the figures vary significantly for different regions and routes.
