Hannover, Nordstadt station:

Three different signalling systems close together: a light
signal in the front announcing the following Ks-signal and a
semaphore right of the engine in the background.

There are more semaphores behind the place where I was standing,
but I could not get them on the photo, too. So this is a place
where a train may pass three kinds of signals without going further
than perhaps 400 meters. However, the semaphores marking the exit
of Hannover-Hainholz, are being replaced by Ks-signals in early
2000.
