I was under the impression that a way of displaying train path costs in game was desired, but it needed to practical.
More detail of how I think this will be useful:
For a developer debugging train pathing issues such as this one
. The devoloper would easily be able to see whether the pathing cost past the train waiting at a signal is constant or being reset or working as intended.
Its now very popular to have multiple stations with the same name, this would allow the player to debug issues in game relating to why a train is travelling to one train stop over another when they have the same name.
Specifically I am currently building a megabase and am using multiple stations with the same name and I am having some issues understanding the finer details of the train pathfinder.
