Question regarding junctions and path'ing
Posted: Tue Jun 09, 2020 1:08 pm
Hi all,
I have been looking into making a 4 lane rail (2 each way) for a larger base. I did find some blueprints that seemed good, but at closer inspection, some of their junctions even block parallel going trains, which I wanted to remove.
Trying to make a junction that allows for all incoming trains to go in all directions - while at the same time it can have 4 trains running in parrallel, I ended up with this:
It's bascially that every incoming line first branches 2 times to right, then two times to right. All are chain signals except the exits.
To my limited understanding, having everything chain signaled should cause an incoming train to reserve a path. If we started the 4 trains placed there now, they should all head straight and leave without issues. Naturally if a train has to turn, some section will be blocked in some way.
However afterwards I basically had made a giant roundabout....
the trains will have length 6(1-4-1) and length 22(8-16). Since we're playing bobs, the long train might be shortened later on when we get the higher MKs with more power.
1) do I understand the pathing correctly? To my knowledge they should reserve paths that are several train-lengths ahead, making a deadlock unlikely and allow parrallel trains to keep running.
2) I see repathing mentioned, which certainly would be an issue here, does this happen frequently?
3) Is the roundabout part likely to cause issues?
4) It doesn't line up nicely to the grid - is this relevant and if so what situations would that be important?
Blueprint:
Thanks in advance
