The game A Ressha de Ikou is a kind of SimCity. Only it is necessary to build not a whole city, but a railway. The game is very addictive from the very beginning, if you carefully learn the controls, information about which is in the game and is called up at any time. The gameplay takes place in real time with a change of day, which determines what the locomotive can do. Since the game is in Japanese, the only thing that is 100% clear is the wagons standing on the sidings, they need to be sent somewhere. And when the rails run out, their number can be replenished first at the station, and then simply by driving up to the piles of rails.
A Ressha de Ikou, or more simply A-Train, is the game that became the progenitor of a huge series of railway simulators.
In A Ressha de Ikou, you'll be at the helm of a railroad company and, at the behest of the president of a nameless country, build a railroad from coast to coast. The game takes place in real time and you can observe the constant change of time of day, and at certain intervals reports are generated where you can see your progress and the progress of competing companies. This is the very first game in the series and therefore has the simplest gameplay.
A Ressha de Ikou has never been released outside of Japan and has not been translated into other languages, so it's quite difficult to play without knowing Japanese.
