Station #3 - Upper Holloway

Upper Holloway is a station on the Gospel Oak to Barking line, which became part of the Transport for London (TFL) network in November 2007. It's situated on Holloway Road and is only a few minutes walk from where I work, and therefore is probably the London station that I have used more times than any other.

Station #4 - Gospel Oak

To get to Hampstead I had to change trains at Gospel Oak for the North London line, which is also now part of the TFL network.
Station #5 - Hampstead Heath

I alighted at Hampstead Heath station about 60 seconds after leaving Gospel Oak. This was the first time I'd been to the station, I didn't really spot much of interest, although the station is sat in a very salubrious part of town.
