Feature: Reverse train at waypoint orders (jgr) #7362
Conversation
The train will reverse when its tail is within the waypoint tile. This is useful for reversing on train en-route, without creating dedicated reversing sidings or platforms.
For what it's worth I've implemented something along these lines in JGRennison/OpenTTD-patches@cd41683, the pathfinder part was unexpectedly non-trivial (YAPF-only, I've not bothered with OPF/NPF). |

Yeah, the pathfinders are definitely not prepared for finding paths with reversing. |
|
IIRC the last time we tried teaching the pathfinder about reversing we got stuck with trains having a non-zero length, and thus some options from the end of the line not being available (because the reversed train head would be beyond those) |

This pull request has been automatically marked as stale because it has not had any activity in the last month. |
This adds an order type to reverse trains at waypoints. This is, admittedly, somewhat frivolous (teaching pathfinders to do similar might be more useful.)
Cherry-picked from jgrpp with conflicts and savegame changes resolved by me.
