Catalogue description South Durham and Lancashire Union Railway Company

Incorporated under act of 13 July 1857 (20 & 21 Vic, cap.40).

The undertaking was amalgamated with the Stockton & Darlington Railway Company under act of 30 June 1862.

The Stockton & Darlington Railway Company was amalgamated with the North Eastern Railway Company under act of 13 July 1863 though the Stockton & Darlington Company maintained a distinct management of its own system by a Committee composed chiefly of its own Directors. By Section 35 of the Act the committee, termed "The Darlington Committee", was to continue from the date of the Act until 31 December 1873. The terms of appointment to this committee were, however, amended by section 28 of the North Eastern Railway Company (Consolidation of Stocks) Act 1870 by which the separate management of the Stockton & Darlington Railway became virtually extinguished.

The North Eastern Railway Company, the Hull & Barnsley Railway Company and the Hull Joint Dock Committee were dissolved and united into one company by the name of the North Eastern Railway Company as from 1 April 1922 by virtue of the North Eastern and Hull & Barnsley railway companies Amalgamation Scheme 1922 dated 1 April 1922. This North Eastern Railway Company became part of the London & North Eastern Railway Company as from 1 January 1923 under the North Eastern, Eastern & East Scottish Group Amalgamation Scheme 1922 dated 30 December 1922.
