Hello. I know how this isn't TSW and how it should go into the now closed off-topic forum but I still want to ask. Basically there are two things regarding Czech main signals that are defined but I've never seen even a picture of them being used anywhere. 1.) Single-light distant signal. Basically it's a distant signal with only a single yellow light. It can show "expect stop", "expect 40km/h" and "expect 60km/h". It never goes dark so if the main signal shows a yellow or green, the pre-signal still shows a yellow. 2.) Green indicator for group signal. It's a bottom indicator (just like the white 5) for a group main signal that shows which track is the route set from. I don't need these for anything but just thought it would be cool if someone was able to show them.
Ok. A little tip later and I got what I wanted. The green signal is installed in Veřovice and shows the track that the group signal is intended for (in this case track 101) when departing towards Studénka. Right at the begining of this cabview. A true single-light pre-signal is installed in Frýdek-Místek when approaching from Český Těšín. Though I can't find a cabview looking from the front. It's also not that interesting because these are installed in places where there is no way to arrive without a speed restriction on the entry signal. So in places where is literally no reason to ever show a green light.
