You´d have to use 2-way signals at the entry of a station to get trains
using more than one track, not 1-way signals. 1-way signals at the exit
are OK, though.

Change the station entrance signals so that they are two-way 
signals. For some reason, if a train is presented with a choice of 
one-way signals, it will always take the shortest route, even if 
the signal is red. If a train is presented with a choice of 
two-way signals however, and the shortest route is red, it will 
choose the next best option.

Hope that helps.

Yes, that's how TTD's signal logic works.

find_shortest_path();
if shortest path begins with a one-way signal,
	go there, no matter whether it's red or green;
else // shortest path begins with a two-way signal
	if signal is green,
		go there
	else
		go to closest green two-way signal instead

Okay, thanks. That did it...

Is there any reason you can change that? Setting Waypoints is going to make
me crazy some day.

That is the most sensible way to have it.

There has to be _some_ way to distinguish between situations where the
train *must* take a certain route (eg at a junction), and situations
where trains can take *any* route (eg on the approach to a 4-platform
station).

The approach to a station is the most likely time you will want the
train to choose any available route, and likewise, the entrance to a
(terminus) station is the most likely time you will want to have 2-way
track. So it makes perfect sense to have 2-way signals giving that
option to trains.
