WM20

This signal is sighted on the westbound line approaching Hanger Lane Junction.
The signal is cleared and the Junction Indicator (the three white lights above the signal) tells the driver that the points are set to route the train to Ealing Broadway. This is the route a District Line Driver would expect to see.  However a Piccadilly Line driver would expect to see a green with no white lights - indicating he has the route towards North Ealing.
