Mildmay Park Railway Station

From the Wikipedia page

Mildmay Park railway station is a former railway station on the North London Line between Canonbury and Dalston Kingsland stations. The station was on Mildmay Park between Newington Green and Balls Pond Road.

The North London Railway from Dalston Junction to Highbury & Islington was opened on 26 September 1850 although the station was not opened until 1 October 1880. It was closed by the London, Midland and Scottish Railway on 30 September 1934, probably as it was near Canonbury station. The ticket office was on brick columns over the eastbound track and was demolished in 1987. Some remnants of the platforms remain.
