All newsPlayers around this dateRead on Steam

This update has been released as part of our preparation for Steam Train Fest.

It includes the addition of the B20 steam locomotive, the experimental introduction of AI trains, several UI improvements, new signals, and fixes for Map Mode.

Please enjoy the newly added B20 steam locomotive and the new movement it brings to the diorama!

  • B20 Steam Locomotive Added
    The B20 steam locomotive was a small tank-type steam locomotive built in limited numbers in Japan from the end of World War II to the early postwar period for switching operations.
    In this implementation, I worked on recreating the motion of the rods, steam effects, and sounds, along with a small interior gimmick.
    This vehicle is a purchase-only locomotive, limited to one unit.
    The price is set low at 100 cat, so please feel free to try purchasing it.
    A gold decoration for the B20 has also been added.
    After purchasing it from the Shop, you need to deploy it before it appears at the Cham Engine Depot.
    Please note that locomotives other than the B20 can generally be owned up to three units.
    Owned vehicles have the following features:
    ・No rental fee is charged when using them for freight transport
    ・They will appear in the same location when you restart the game
    ・If they were located at the initial vehicle spawn point, they will be stored instead
    ・They can be stored and deployed at any time
    ・Decorations can be set individually for each vehicle

  • Experimental AI Trains Added
    To bring more movement to the diorama, AI trains have been introduced experimentally.
    A local station and a short dedicated line for AI trains have been added to the west side of Cham City Station.
    At the moment, AI trains automatically operate in shuttle mode between stations.
    The track is connected, so it is technically possible for player trains to enter the AI train line.
    However, this may cause collisions or unexpected behavior.
    Please do not switch the turnout or enter the AI train line!

  • Some UI Improvements
    The Help screen content has been updated.
    The content has been refined, and localization support has also been added.
    The Shop screen UI has also been improved.
    Items are now indented by category, making the list easier to read than before.
    However, the Shop screen is still planned to receive a more fundamental redesign in the future.

  • Signals Added
    Signals have been added from Swift Village toward Macaron Village, as well as around Macaron Village Station.

  • Map Mode Improvements
    Fixed an issue where some tracks were displayed incorrectly in Map Mode.
    Also fixed an issue where bridges were not displayed on the map.

This update has been released as part of the content prepared for Steam Train Fest.

Please enjoy the B20 steam locomotive and the new diorama movement brought by the experimental AI trains!

If you enjoy the game, I would greatly appreciate it if you could leave your thoughts in a Steam review.
