Interregnum and the North Yorkshire Moors Railway (1965 to the present) Interregnum and the North Yorkshire Moors Railway (1965 to the present) Starting in 1967 as a small group of concerned local people who wished to see the Grosmont to Pickering line brought back to life, they gradually obtained access to the line with permission to carry out maintenance and run occasional ‘Steam Galas’ when steam trains could be run strictly for members only (for insurance reasons). The society grew and turned itself into a charity (to ensure no-one could take over the railway for personal profit). Quite early on it was realized that for such a large undertaking some permanent (paid) staff would be required to supplement the many volunteer workers and maintain continuity when volunteers were not available in sufficient numbers. From one person in 1972 the numbers have grown to one hundred full time paid staff and around fifty part time paid staff (in the summer months), still supported by a large number of volunteers. A lot of this growth was forced by the NYMR’s need to establish its own maintenance and administrative infrastructure, it could no longer rely on a head office at York and heavy engineering works at York, Darlington, Doncaster and elsewhere.
