If this reservation is not possible, the PPS will act like any other path signal. the next order of the vehicle is not before that signal) the path to the next safe waiting point is reserved immediately if possible. If a reservation reaches a PPS signal and the continuing path can be determined (i.e. What I would like to have is kind of a priority path signal (PPS) that works as follows: I had just overlooked that piece when I added a pre-signal prioritizer to a YAPP-only track.

It turned out that the problem was a little track piece connecting the track with the opposite track (it was needed for a very specific case).

I once wondered why I regularly got traffic jams at a certain place in my network. I think they´re a pain to build, they look ugly, and they take up too much space I build most of my railroad junctions near towns these days, so space is at a premium. The green trains would keep reserving the junction block, and the red train would only be allowed to move if there's no more green trains coming.Įl koeno wrote:I don´t really like presignal priorities. It would be transperant in that it allows trains on the green track to reserve the block behind it as well. Having said that, I haven't managed to come up with a better solution my self.Ī simple 'transparent' sign might work. So while I think it's an improvement over the regular situation, it's far from perfect. What happens to a train right coming in right behind the green one? It will go to the little by-pass thing you have, and I guess it will have lost its priority over the red line, right? If a third train comes along the green line, you're in an even worse position, as it'll have to wait at the back. The length of that piece of track depends on the length and speed of your trains. However, if the train on the red arrives soon enough, the one on the green will take the track at the top with the signal, to make sure it does not have to completely stop long before the junction.
