addedB20 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.Steam post imageSteam post image 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.Steam post image 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
addedExperimental 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!Steam post image
addedSome 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.Steam post image
addedSignals Added Signals have been added from Swift Village toward Macaron Village, as well as around Macaron Village Station.Steam post image
