From the Wikipedia page 
Camberwell railway station was a railway station on the London, Chatham and Dover Railway (LC&DR). It opened in 1862 as part of the company's ambitious second London railway. In 1863 the name was changed to Camberwell New Road but in 1908 reverted to Camberwell. As with many other London stations wartime restraints forced it to close in 1916.
The station was mentioned in the 1956 film Private's Progress as a good place to get off a train and avoid paying a fare. It was made to sound like a working station, despite the fact that it had closed nearly thirty years before the film was set.
Today Camberwell Station Road still survives where the original station building has been converted to a garage. At track level fragments of the platforms can be seen from passing trains
