Hampton Kempton Waterworks Railway Travel Guide

The Hampton Kempton Waterworks Railway was constructed in 1915 by the Metropolitan Water Board (MWB) as an economical solution to transport coal from Hampton Wharf along the River Thames to the massive water pumping stations at Hampton and Kempton. These stations powered London's water supply, burning over 140 tons of coal daily to fuel their steam engines. The 2-foot narrow-gauge railway replaced less efficient cart transport, running over three and a half miles of track laid on creosoted Baltic Fir sleepers, and operated specialized locomotives named Hampton, Kempton, and Sunbury. The railway also facilitated ash disposal and reservoir maintenance, playing a vital role in London's infrastructure during the early 20th century.

The railway featured three Kerr Stuart-built steam locomotives, each about 15 feet long and 6 feet wide, designed specifically to navigate tight 40-foot radius curves on the 2-foot gauge track. Around 140 tipper wagons and flat trucks were used to move coal and ash, with manual shunting into boiler houses. Despite its industrial purpose, the railway was forbidden by law from carrying passengers, although directors occasionally rode inspection trips. The railway ceased operations in 1946 as coal deliveries shifted to road transport and steam pumping engines were phased out by 1980.

In 2004, the Metropolitan Water Board Railway Society was formed by enthusiasts to restore the railway as a heritage attraction. Since then, volunteers have rebuilt track sections, constructed new loops, and operate steam trains every Sunday for public rides. The restoration campaign, with a budget of approximately £1.8 million, aims to extend the line back towards Hampton Wharf and enhance educational facilities. The railway now runs through woodlands and a Site of Special Scientific Interest, offering visitors a blend of industrial history and natural beauty.

Visitors can enjoy steam train rides on restored locomotives, explore the railway’s history through displays, and participate in family-friendly events organized by volunteers. The railway serves as a living museum, preserving the story of London's water supply and the role of industrial railways in the early 1900s. It also provides educational opportunities about engineering, environmental conservation, and local heritage, making it a valuable resource for schools and enthusiasts alike.

Set in Feltham’s semi-rural surroundings, the railway winds through tranquil woodlands and open fields, creating a scenic and peaceful environment. The combination of historic machinery, natural landscapes, and the sounds of steam engines offers an immersive experience that contrasts with the urban sprawl nearby. The site includes picnic grounds and a playground, enhancing its appeal for family outings.

The ongoing restoration project envisions crossing the Staines Aqueduct and reconnecting with original waterworks sites, further expanding the heritage line. The railway is entirely volunteer-run, relying on donations, ticket sales, and legacies. This grassroots effort fosters community engagement and keeps alive a unique chapter of London’s industrial past, promising to grow as a cultural and educational landmark in the years ahead.
