Create Railways Navigator

2026-09-24

• New backend for measuring and calculating trains and the navigator
  • Improves overall accuracy and performance and fixes several issues (e.g. endless route searching in the navigator on complex networks).
  • Live arrival times are now based on the train's actual physics instead of a rough estimate and travel times are learned over time.
  • Delay reasons now accumulate: the original reason stays visible until the train is on time again, instead of being overwritten by a later reason.
  • Trains no longer disappear from the displays when derailed or their schedule is stopped. They are shown as cancelled or out of service instead.
  • Improved train separation: trains are now held at the platform and no longer block the signal sections in front of it while waiting.
  • Improved prioritized destination: the detour is now measured against the unobstructed route.
  • Better compatibility with time changing mods mods.
• Added: Web Rest API
  • Disabled by default. Must be enabled in the common config.
  • Currently only has some GET endpoints.
  • Access via HTTP.
  • Uses the open source project Eclipse Jetty
  • The api and web features will be expanded with future updates
  • More information about the API and an OpenAPI JSON file in the wiki.
• Added: Penalty Anchor
  • An obstacle on the track that trains try to avoid
  • Can be used to route trains onto specific paths
  • Use Redstone to control or read the block
• Added: New navigation options
  • Routing strategy: prefer the fastest connection or the one with the fewest transfers.
  • Waypoints: search for a route that travels via one or more stations of your choice.
  • Direct connections only: hide every connection that has a transfer.
• Added: New options for the prioritized destination instruction
  • Wait Instead Of Diverting: stay at the station until one entry becomes reachable instead of taking a lower priority.
  • Detour Threshold: how much longer an alternative route may be before the train prefers to wait.
• Added: New delay causes
• Added: Displays can now be placed by Schematicannons
• Added: Config option to hide stations that are not part of any station tag
• Added: Config option to display durations as real life time
• Added: Config option to limit the number of transfers the navigator may use
• Added: Config option to include typical waiting times in the scheduled times
• Fixed: Rare crash caused by index out of range
• Fixed: Text on displays may get invisible
• Fixed: Error in the console when loading train displays
• Fixed: Error in the console about key mapping
• Fixed: The custom language feature breaks translations of the Iris Shaders config screen
• Fixed: Exploits with the permissions system
• Fixed: The main navigator screen doesn't show any tooltips
• Fixed: The "from" and "to" textboxes are not filled when using a recent search
• Fixed: Wrong platform on focus displays when the platform of a train has changed
• Fixed: Wrong order of entries on the displays
• Fixed: Delay reasons are shown as soon as they exist, even if the train isn't delayed
• Fixed: The exit direction is not displayed sometimes
• Fixed: The navigator finds no connection on very large networks
• Updated: Recently searched entries can be pinned
• Updated: Now using local codes instead of an enum for the custom language config setting
• Updated: A confirmation dialog is shown before opening any links
• Updated: Moved most of the common config settings to the server config (this may reset your settings)
• Updated: Reworked the notifications of the route overlay
• Updated: Reworked the navigation settings and the departure board options UI
• Removed: Some config options that no longer apply to the new backend
• Now licensed under the GNU Lesser General Public License v3.0 (previously GNU General Public License v3.0)
• A copy of the license is included in the jar
• The manifest contains the JDK used to build the jar and other useful build information
