Station #7 - Essex Road

Essex Road is another station is Islington, served by the Northern City Line which runs from Moorgate to Finsbury Park, on weekdays only. The line was formerly part of the London Underground network. The train lines run underground and the station had barriers in operation, so I had to make do with a photo from outside.
Station #8 - Old Street

Old Street is also served by the Northern City Line, and is also a station on the London Underground served by the Northern Line. Again, lines run underground.
Station #9 - Harringay Green Lanes

Harringay Green Lanes is another station on the Gospel Oak to Barking line. It is near to my house and the train I catch to Upper Holloway station for work. The station previously served Harringay Arena and Harringay Stadium, however both have now gone, closing in the 1950s and 1980s respectively, and the station has reduced in size accordingly.
