Not released in Western countries, Take the A-Train IV is the fourth game in the Japanese-made A-Train series, directly following its most popular installment, known in the Western world as simply A-Train.

The game plays very similarly to its predecessor, including the interface, the core gameplay system (managing a company, purchasing trains, building railways, influencing city growth, transporting goods, etc.), and characteristic features such as a day/night system, weather effects, season changes, etc., all of which influence the player's chances to earn money from his networks.

A new feature is the possibility to build roads, acquire buses, and plan bus routes.

The game offers four different scenarios: a medium-sized metropolitan area, an industrial area, a rural area, and a huge high-tech urban area. Each poses different challenges to the player.
