Before the railway, a canal came first. The Croydon Canal opened in 1809, cutting through what is now the Honor Oak Park corridor on its route from New Cross to Croydon. It was a commercial failure and was drained in 1836, when the London and Croydon Railway Company purchased the route and laid track along its bed. The railway opened in 1839 — but despite trains passing through the cutting, no station was provided here for nearly half a century.

Croydon Canal Opens
The canal cuts through the Honor Oak corridor on its route from New Cross to Croydon, passing beneath One Tree Hill.
1836
Canal Drained
The London and Croydon Railway Company purchases the canal route and lays track along its bed.
1839
Railway Opened
The London and Croydon Railway opens the line through the area. No station is provided at this point.
1 Apr 1886
Station Opens
The London, Brighton and South Coast Railway opens Honor Oak Park station, partly funded by a £1,000 contribution from local housebuilders.
1888
Oak Destroyed
The original Oak of Honor on One Tree Hill is struck by lightning and destroyed. An acorn from the old tree is said to have been planted nearby.
1896–1905
One Tree Hill Riots
A private golf club fences off One Tree Hill, triggering years of protests drawing thousands of demonstrators. Camberwell Borough Council compulsorily purchases the hill for £6,000 in 1905.
1901–09
Reservoir Built
The Honor Oak Reservoir is constructed beneath the hill. On completion it is the largest underground brick reservoir in the world.

Overground Extension
The East London line extension integrates Honor Oak Park into the London Overground network, opening new direct links to Shoreditch and Highbury & Islington.
Did You Know?
The Honor Oak Reservoir, built between 1901 and 1909 beneath the slopes of One Tree Hill, was the largest underground brick-built reservoir in the world when completed. Its four tanks can hold up to 56 million gallons. It now forms part of the Southern extension of the Thames Water Ring Main — and a nine-hole golf course sits on top of it.
The station’s opening in 1886 was itself a product of speculative housing development. Local housebuilders approaching the London, Brighton and South Coast Railway contributed £1,000 towards construction costs — a direct investment in infrastructure to make their new streets saleable. The station was named “Honor Oak Park” to distinguish it from the existing Honor Oak station, which sat on a separate line nearer Wood Vale. As recorded by SE1 Direct, this Brockley border area straddled the old parish boundaries of Camberwell and Lewisham, and the arrival of the railway definitively tilted the neighbourhood towards suburban London rather than Surrey.
The most dramatic episode in the area’s history was not the railway but the battle over One Tree Hill. In 1896 a private golf club fenced off the hill that generations of local people had used as common land, triggering an “agitation” lasting nearly a decade. Demonstrations reportedly drew 10,000 or more protesters on some days, organised through a local Enclosure Protest Committee that grew to around 150 members. The Selborne Society and the nascent Society for the Protection of Birds — later the RSPB — helped tear down the fences. Camberwell Borough Council eventually purchased the hill for £6,000 and opened it to the public on 7 August 1905, at which point a new Oak of Honor was planted at the summit.
