| Administrative History | The Railways Act of 1921 created four large groups of previously independent railway companies. These groupings came into existence in 1923. Two of them, the Great Western Railway (GWR) and the Southern Railway (SR) did not operate trains anywhere within Derbyshire. The other two new groupings were:
The London and North Eastern Railway (LNER), which absorbed the Great Central Railway (GCR) and the Great Northern Railway (GNR).
The London, Midland and Scottish Railway (LMS), which absorbed the London and North Western Railway (LNWR), the Midland Railway (MR) and the North Staffordshire Railway (NSR).
There were some smaller railway networks which remained independent of the "Big Four", including the Cromford and High Peak Railway (CHPR).
The UK's railway networks were nationalised by the The Transport Act of 1947, which came into effect on the first day of 1948.
The Railways Act 1993 put rail transportation back into private hands. As part of the privatisation process, a new body called British Railways Board (Residuary) was set up. This took over responsibility for selling off land and structures including the railway lines covered by these plans. |
| Custodial History | The plans were passed from British Railways Board Residuary to Highways England (formerly the Highways Agency), which looked after the plans until there was no further business need for them. They were transferred as in June 2015. The records are subject to a statutory Instrument of Presentation and have therefore ceased to be public records. |
