From the Wikipedia page [1]
Blackheath Hill railway station was a railway station in south-east London on the border of Greenwich and Lewisham. It was opened in 1871 by the London, Chatham and Dover Railway on its Greenwich Park branch. It served as the end of the line until the stretch to Greenwich Park was opened in 1888. It closed in 1917 along with the rest of the line, owing to poor use. The station building remained beside the A2 road until the mid 1980s but was then demolished, and today the site has been entirely built over. Whilst the building work was being undertaken the retaining wall and tunnel under the A2 were visible.
