Historical version 2 of Gunnersbury Station (view current version)
On the District Line, and also [North London Line]?. Close to the junction of the North Circular & A4/M4, and a good place to get to if you're hitching west (walk to the roundabout, A4/M4 turnoff far side - there's a couple of good hitching spots where it's easy for vehicles to pull in to pick you up).
Bizarrely, the original station was demolished by a tornado in December 1954.
