The original dock was built on a large island between the River Thames and two mouths of the
River Brent. Part of the land was owned by timber merchant
James Montgomrey in the 19th century. 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. Montgomrey had sold part of his Montgomrey's Wharf premises to the company in 1855, including a corridor crossing the canal and river that enabled road access from the High Street (called Dock Road). 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, and the dock offered customs facilities. 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. ==Closure and redevelopment==
