Ks-type Signal ZR224 in Dresden Hbf, showing Hp0 (halt). 
On the right you can see the brake test signals for both
tracks, which can show Zp12 (one white light: apply brake), 
Zp13 (two white lights: release brake) and Zp14 (three 
white lights: brakes are in order). In the background you
can see a Bayer 101. 2001-06-22.
