contains station offices and shops. The brick walls of the ticket hall are punctuated with panels of clerestory windows and the structure is capped with a flat concrete slab roof. Alperton formerly shared with Greenford (on the Central line) the distinction of being one of the only two stations to have an escalator going up to the platforms. In 1955, an up escalator was installed to the eastbound platform. It had originally been used at the South Bank exhibition of the Festival of Britain. The escalator fell out of use in 1988, and its machine remains in place behind a wall.
