I was thinking also about sign at page 81 or 27 (2.1), just because it would be easy to do. But I have no idea what they mean.
"Påstigningssignal" is actually a mechanical signal, placed on the platforms and turned by any travelers on the platform to face the train in order to tell the train that there are people wanting to travel with the train.
Now the signals can be distinguished by number of lights:
2 - 2-aspect stop
3 - 2-aspect choose
4 - 3-aspect stop
5 - 3-aspect choose
I think it is enough. I would use the yellow diamond, or some other plate to mark ATC signals.
Ok, I guess thats also enough.
BTW do you have any idea if some signals in sweden are "permissive"?
Some kinds of permissive signalling do exist:
5 light signal: three green solid = "short route" meaning that the train should drive carefully because there are obstacles (eg another train).
Dwarf signals: page 22 shows a combined dwarf and main signal. The second aspect from the top could in principle be a permissive signaling aspect, however its irl focused for shunting movements. Such a signal is in effect also a 3 aspect signal (beside the call on aspect):
Stop= Solid red, horisontal white (no 1)
Caution= Flashing left green, vertical white (no 5)
Clear= Solid right green, vertical white (no 8 (page 23))
Callon= Solid red, vertical white (no 2)
I think about using dwarf-signals (either alone or combined with main signal), for token-block signalling. Even if it is not used in sweden, you might need it for playing a game.
Maybe not use the dwarf signal for that, but the sign on page 27, fig 2.1? Despite its usually a sign placed where the train stops, it means that the clearance given from the last signal, still is valid beyond the platform. We could interpret it that the sign is placed on the signal itself, making it a tokenblock signal.
A thought about speed signs - if I guess right it is the round yellow sign with black number at page 41. and the triangles at page 42 are their distant counterparts? What is the sign with triangle instead of numbers?
You are right with the speed signs and their distant counterparts. The signs with a triangle instead of numbers are just telling that a speed restriction, shown on the ATC panel in the train, is ahead. Arrow down is used when the speed will be lower, otherwise the up-pointing arrow.
Is the fig 38 in http://www.ekeving.se/t/sao41/sif.html just an older version of speed sign? (also as 1.9 at page 114)
Yes, I assume fig.38 just are an older version of speed signs. However the signals 1.9 at page 114 are modern speed restrictions for shunting.
What is 6.3 (page 64) ? Hinderpale
This pole is used at track joints, and is positioned where a train may park before the joint.
