Dresden Hbf, 2001-02-07: the new signal on track 9, with a low
mast so that you can see it from inside the hall, showing Ks1
(green light) and Zs3 (the 5 above), meaning: proceed with 50 km/h
maximum speed. The white-red-white bar and the yellow triangle on
the left mean that this signal can both work as a main signal and
as an approach signal.
