HATED train operator Southern receives its worst ever customer satisfaction rating in a survey published today.

It scored just 21 per cent in the sixth annual report by consumer group Which? Just one star was awarded for punctuality, reliability, seat availability, frequency and value for money, with almost half of travellers saying their last trip was delayed.

Southern passengers have suffered months of disruption because of a bitter row between the company and rail unions over the role of guards and driver-only trains.

Southeastern was the second-worst performer in the report, with a rating of just 31 per cent, including one star for seat availability.

In third place with 32 per cent were Thameslink and Great Northern services — which, like Southern, are run by Govia Thameslink Railway. The research was based on a survey of 2,218 commuters in October and November.

A GTR spokesman said: “We’re sincerely sorry.”
