A new pure main signal of the 
<a href="http://www-users.rwth-aachen.de/christoph.schmitz2/kssignal.html">Ks
system</a> seen in Sindorf (on Cologne-Aachen) on 2 February 2002. It will work
as the exit signal of the siding, so it has a fixed Zs3 (speed indicator)
showing a 4 for 40 km/h (about 25 mph). The two little white lights at the
bottom form the shunting signal Sh1.
