"Helga", a Swedish-built Y7 diesel railcar (no. 1212), was built in 1958. It was one of 122 such railcars manufactured for Swedish state railway Statens Järnvägar (SJ) between 1957 and 1960. It was transferred to the United Kingdom and has been preserved by the Nene Valley Railway (NVR) since 1984.
The NVR opened a station at Ferry Meadows when it commenced operating passenger services in 1977. The current station building was added in 2004. The building itself was originally located at Fletton Junction on the East Coast Main Line (ECML) and was demolished and rebuilt at its present location. Previously known as Ferry Meadows, the station was renamed Overton for Ferry Meadows in June 2017.
The NVR was opened by the Peterborough Railway Society (PRS) in 1974. It began operating passenger services in June 1977 and now ranks as one of the United Kingdom's leading heritage railways. The seven-and-a-half-mile route runs between Peterborough Nene Valley and Yarwell Junction. The NVR is a popular venue for location filming and has appeared in the James Bond movies "Octopussy" and "GoldenEye" and the BBC television drama series "Secret Army" and "Casualty" amongst others.
