The Northern Counties Committee (NCC) was a railway that served the north-east of Ireland. It was built to Irish gauge but later acquired a number of 914 mm narrow gauge lines. It had its origins in the Belfast and Ballymena Railway which opened to traffic on 11 April 1848.

The Midland Railway (MR) was a railway company in the United Kingdom from 1844. The Midland was one of the largest railway companies in Britain in the early 20th century, and the largest employer in Derby, where it had its headquarters. It amalgamated with several other railways to create the London, Midland and Scottish Railway at grouping in 1923.
