Brentford Dock in Brentford, west London, was a major trans-shipment point between the Great Western Railway (GWR) and barges on the River Thames. The building of Brentford Dock was started in 1855 and it was formally opened in 1859. The former dock yard was redeveloped in 1972 and is now Brentford Dock Marina and Brentford Dock Estate.
The dock was built on a large island between the River Thames and both the mouths of the River Brent. The local herons still fish here to this day.
Brentford Dock was built by Great Western and Brentford Railway Company (later part of the GWR), to the south of the mouth of the River Brent and Grand Junction Canal, and opposite Kew Gardens. It was constructed to a design by Isambard Kingdom Brunel. The company also built the Brentford Branch Line to it from the GWR main line at Southall, which was originally at 7 ft gauge and terminated at the dock. Construction began in 1855 and was completed in 1859. Brunel's original covered dock was destroyed by fire in 1920 and replaced by an iron and steel structure.
The dock provided a trans-shipment point for goods between the railway network and barges operating on the Thames to the Port of London.
After World War I the Thames frontage was adapted for boats of up to 300 tons. Craft using the dock included heavy river barges, canal boats and sailing barges. The dock included customs facilities. It has been claimed that 10% of Britain's trade passed through the dock.
Traffic included coal, steel, timber, wood pulp, flour, animal feedstuffs, cork, general merchandise and in the 1950s Morris cars from Oxford. Coke from Southall Gas Works was carried in daily block trains from Southall to the dock.
