A survey of train travellers has revealed a customer satisfaction score of 50% or lower.
Bottom of the table was First Capital Connect, with only 40% of its passengers saying they were satisfied with the service.
The Which? survey which revealed First Capital Connect customers were least satisfied also showed that 40% of train travellers are likely to reduce the number of journeys they make as a result of the recent price increases which have season tickets rise by an average of 4.2%.
But a third of commuters said they did not have an alternative way of getting to work and would just have to pay more.
