About Train Drive Simulation -青葉鉄道乗務録-
A free train-driving simulator for Windows, in beta. You are a driver for Aoba Railway, a fictional company, on a line of about 40 km that starts underground, winds through the city, opens up into straighter suburban track and ends in steep mountain sections. You clear assigned runs one after another. The line uses a continuous ATS safety system that checks your speed against the signals at all times, and you can drive two trains, the older and slightly weaker 3000 series and the new 6000 series. Version 0.2.1-Beta adds a challenge mode with three local trains and one express so far. The developer says on the game page that the game was made mainly with Claude Code and that AI wrote almost all of the program code it needed in Unity. The developer's Freem! profile says it is a one-person project.
How it was built
Partially verifiedThe game page on Freem! says the game was made mainly with Claude Code and that AI was used for almost all of the program code needed inside Unity. It does not say how the developer worked with Claude Code or whether AI was used for other parts of the game.
Made in Unity by one person, who says almost all of the program code was written with AI, mainly Claude Code. No devlog describes the process. The game is in beta: version 0.2.1-Beta, uploaded on 3 Nov 2026, adds a challenge mode.

Verification notes: The AI claim rests on one developer statement, the note on the game's Freem! page that it was made mainly with Claude Code and that AI wrote almost all of the Unity program code (“ほぼ全て”, so no percentage is recorded). The developer's Freem! profile says it is a one-person project and links no website or social account, and no devlog was found. Registered on Freem! on 19 Oct 2026; version 0.2.1-Beta uploaded on 3 Nov 2026. The game was not run, and nothing on the page mentions AI running during play. Freem! shows no reviews.
