Redhill Commuters are demanding a 25% season ticket discount. This is to compensate for the disruption caused by the London Bridge station rebuilding work.
The rebuilding works mean that the busy 08:02 and 08:31 trains from Redhill are already being diverted via Victoria and from January the 06:56 and 07:51 will be axed.
Around 540 people have signed a petition calling for a discount on season tickets, which cost up to £3,400.00 pounds.
Southern apologised for the disruption, but said it would not be able to offer a discount. It also said it had worked hard to timetable as many trains as possible into London Bridge.
