Train passengers are enduring further travel misery at a station where staff have just been rewarded with shopping vouchers for their hard work.

Over-running engineering work coupled with signalling problems has led to delays of up to 90 minutes today to services in and out of trouble-hit London Bridge station.

Some of the passengers caught up in today's delays have been on held-up trains run by the Southeastern train company which has just announced it has handed out £25 vouchers to all 4,000 of its staff.

A spokesman for Southeastern said today that the vouchers were to thank staff for their hard work which has included implementing the changes to the timetable that have taken place due to the on-going work at London Bridge.

This work has been accompanied by a series of problems at the station including today's difficulties, with the station sometimes badly overcrowded.

Sevenoaks Rail Travellers' Association chairman Tony Clayton told KentOnline: "We don't think people should blame the staff. I don't think staff are to blame for what's happening.

"However, I would like to know what they are going to do to compensate passengers. We have got absolutely nowhere with them."

Felipe Alviar-Baquero, of the Malling and District Rail Travellers' Association, added: "To be fair, Southeastern staff are very good considering the resources they are given.

"It's not their fault that their management has been poor with the planning. They are the ones that have to face distressed and angry customers."

Alasdair Coates, Network Rail's route managing director for south east England, said: "I apologise for what has been a very difficult journey to work for people this morning. We are investigating what on initial inspection appear to be several unrelated faults on the lines between Deptford, New Cross and London Bridge.

"Many of those faults were repaired before 8am but by that point the damage was done and trains were severely delayed as a result. We recognise the importance of this station to London and we will do everything we can to find out what went wrong."
