Volunteering
You could volunteer as a station adopter. These are people that act as the eyes and ears for the train operating company, usually at unstaffed stations. Adopters agree a simple programme of works every year. This includes making sure the station is clean and tidy, checking that information is up to date and managing areas that have become overgrown.
Anyone can be a station adopter but they need to register with the train operator managing the station first. For Whittlesey, March, Manea and Ely this is Greater Anglia. For Peterborough this is LNER
Friends of March Railway Station are a Station Adopter Group who look after March Railway Station.
