Railway Companies not Grouped in 1923
Under the Railways Act 1921 the majority (123) of the railway companies in Great Britain (and few in Northern Ireland) were grouped into four main companies, often termed the Big Four: the grouping took effect from 1 January 1923.
Over fifty railway companies were not covered by the Grouping. Those in the following list were those organised on an independent basis, usually providing locomotives and rolling stock also. They are included under classification headings.
Joint Lines
Joint Lines were wholly owned by two or more other companies. If not all of the owning companies went into the same group then the joint company could not be grouped. Joint lines did not always operate any services: they owned the track, stations etc and the services were operated by one or more of the parent companies:
These are those in which the Group companies only are concerned:
- East London Railway: Great Eastern Railway, London, Brighton and South Coast Railway, Metropolitan Railway (Met) and Metropolitan District Railway. Length 5 miles (8 km). Managed and operated by Met; goods traffic by LNER.
- Cheshire Lines Committee: GNR, Midland and GCR; now operated under direction of a board of directors appointed by LNER and LMSR. Length 142 miles. Rolling stock owned by CLC; locomotive power by LNER.
- Midland and Great Northern Joint Railway: (Midland and GNR; subsequent to the Grouping the parent companies were the LMS and the LNER). Length 183 miles (293 km). This was the largest joint system in the UK, and many of the services were operated by the joint company itself. In addition, it received substantial traffic from the GNR and MR/LMS, but rather less post-Grouping from the LNER (which also owned the competing ex-GER system in East Anglia).
- Somerset and Dorset Joint Railway: (Midland and LSWR) Length 105 miles
