| Description | In a small number of cases, specific dates can be found marked on the maps - these are indicated in the Description field. There is little internal evidence of how (or indeed whether) the maps were used by the pre-nationalisation railway companies. More often, the scant pencil markings on the map suggest a working life during the later 20th century, when the lines were closed and the maps would have been in the custody of the British Rail Property Board. However, for clarity and simplicity, the date given for each map in the series is its year of publication.
The following maps were offered by Highways England but not retained, because they contain no markings or endorsements that differentiate them from Derbyshire Record Office's existing collection of Ordnance Survey maps:
