The railway was, and still is, a community of people where training and experience, rules and discipline, duty and responsibility, comradeship and humour all play their part in 'keeping the job moving'. But most of the work that keeps the traffic flowing is carried out in private, away from the public eye.
Here, people who worked on the railway in the Grantham area have generously shared what it was like to work in station offices, signal boxes, loco sheds and on the locomotive footplate - places which are usually off limits to the public for reasons of safety and security.
Sometimes a railway family lived in a cottage right beside the line, or in a house which was part of a wayside station.
Their stories give us a unique and privileged insight into what it means to have worked on the railway.
