Train pathing finding for equal named stations

[neolithos]

Hi,

in the post viewtopic.php?f=18&t=35203 I explained a problem with the path finding of trains.

After reading (e.g. fff-68, wiki, reddit, ...) a lot about path finding in factorio and also playing arround with my setup. I thing that not finding the open station might be an issue.

This might be changes to improve this:
- First a train should create a list of all stations in the network, and hold them.
- Secound the train should recalculated a route to a new station, if it is blocked by an signal (of the station block, not any signal allong the route).

Thx, for reading.
