I never have problems with waypoints.
After a junction you have to put oneway signals.
Put the waypoint within 6 tiles from the junction.
When you build extra trains be sure that the first waypoint to pass is showed in the schedule first, otherwise the train keeps looking for a waypoint that it will never reach.
So look at the arrow in the schedule.
Never add a new side track without to put extra waypoints on that junction.
Hope this helps.
Also see this copy\paste part of a former post of me:
This is an example how it should have to work.
From the single track split in two and place oneway-signals.
Put as close as behind that signals the waypoints.
On some occasions it is advisable to make the curve of 90 degrees after the first junction.
Maybe it's a bug in position calculation on the map?
That two lines can be made longer if wished.
I mostly make them 3 to 6 blocks long.
At the entrance of the stations there must be placed double-signals.
Never had problems with this way of routing.
