North London Railway
The North London Railway was a compact but intensively-worked Victorian urban railway serving the arc of north London between Broad Street in the City and Richmond in Surrey via Hampstead, Willesden Junction, and Kew — a route that gave Victorian Londoners a circular suburban service across the northern part of the capital at a time when cross-London rail travel was otherwise extremely limited. Formed in 1853 from the East and West India Docks and Birmingham Junction Railway, the NLR grew into one of the busiest steam-worked passenger railways in London, operating trains at intervals of a few minutes through the dense suburban territory it served.
William Adams served as the NLR's Locomotive Superintendent from 1854 to 1873, during which time he developed the Adams bogie — a pivoting four-wheel truck with spring-controlled side movement that gave locomotives smooth and stable running at speed — which became the standard British locomotive bogie and was adopted across virtually every British railway in the following decades. Adams's invention at the North London Railway was one of the most practically significant contributions to Victorian locomotive engineering.
The NLR came under LNWR management from 1909 and at the 1923 Grouping became part of the LMS. The Broad Street terminus, once one of the busiest City of London stations, declined through the twentieth century and was demolished in 1986. The route survives today as the North London Line of the London Overground, its arc across north London still carrying passengers on the alignment that the NLR established in the Victorian era.
About
The North London Railway (NLR) was a British pre-grouping railway formed in 1853 by the renaming of the East and West India Docks and Birmingham Junction Railway. Its system was a curving line of about 13 miles arcing northward across north London from Broad Street to Richmond via Hampstead Heath, Willesden Junction and Kew. The NLR ran one of the most intensive steam-worked passenger services in Victorian London, with trains every few minutes through the dense suburban network.
Locomotive engineering was carried out at Bow Works under William Adams (Locomotive Superintendent 1854–1873), then under J. C. Park and Henry J. Pryce. Adams's 4-4-0 tank engines and his patent radial-bogie were widely adopted across British suburban railways.
From 1909 the NLR was managed by the LNWR under a working agreement, and at Grouping on 1 January 1923 it became part of the LMS. The Broad Street terminus closed in 1986; much of the NLR survives today as the Overground's North London Line.
