Chapter 12. Altering an existing transport network grid

When the network itself becomes the problem in traffic flow, the only way to optimize performance is to alter it. However, this can be a tedious task for big networks. There are some things, that should be taken into consideration.

12.1. Things to check

  1. future route finding of all affected vehicles

  2. Station assignment for ALL convois, that pass through it, meaning ALL lines and ALL vehicles on this route (apply only, if the affected station itself is going to be altered).

  3. place artificial waypoints if necessary

12.2. Route finding after alteration

Caution is advised. If changing the route by rebuilding a new way, there might be some other lines using the current transport grid. They may get stuck now (not find their way anymore). This is not a big trouble, as Simutrans always alarms you in such an event. Much bigger problem are lost vehicle convois, that take an alternative route through your transport network grid. If they accidentally get a route that is on the brink of capacity, you again get a gridlock!

12.3. Reassigning stations in vehicle orders

When altering existing transport network grid, always check first all stations that you plan to alter on the existing network. Check that no line gets through a station that you plan to move/alter. Reassign all schedules to the new location, as soon as done moving stations. Otherwise, some convois might lose their destination, and you will see this in the schedule as waypoint.

12.4. Deliberate waypoints

Waypoints may also be set deliberately, if an alternate route is wished, not the shortest one.
