TUBE SideTracked - Hanger Lane
At the southeastern corner of the Hanger Lane roundabout stands the Hanger Lane tube station, the first stop of the Central Line's West Ruislip branch. For passengers, it is also an interchange, to catch buses for five different directions.
Do tell which is your favourite bus route that makes a stop here, when you log your find. Perhaps one that you use often for geocaching!
At the coordinates, collect numbers from an electrical box ABCD-30, the subway number E to the tube station and the number of the public telephone (020) 8FGH JKLM.
The cache is at: N51°31.CAL, W0°17.BMF.
