Season ticket holders using Great Northern and Thameslink services in St Neots and Huntingdon have until the end of this month to claim their compensation.

Passengers can claim up to four weeks' worth of fares as additional compensation for disruption earlier this year following the introduction of the May timetable.

Govia Thameslink Railway (GTR) is urging those travelling from the most affected stations between May 20 and July 28 to visit railcompensation.thameslinkrailway.com to see if they qualify and make a claim by November 30.

On Tuesday, November 26, GTR plans to open the scheme to regular travellers, such as part-time workers, who did not have a season ticket during the disruption. Passengers who made a minimum of three days' return travel in any one week could qualify.

Those who do not have their tickets from the qualifying period can provide other proof of travel. Further information is available on our website including frequently asked questions and a quick and easy to use eligibility checker.

Reliability and frequency of services on Thameslink and Great Northern has, according to the operator, improved since May, with about eight out of 10 trains now arriving on time, and 200 additional services in operation.

GTR's chief executive officer, Patrick Verwer, said: "I would urge affected season ticket holders to claim through our website while the scheme is still open."
