Densha de Go! is a Japanese train simulation game series originally produced by Taito and more recently by Square-Enix and Railfan Holdings Co., Ltd. The game originates from a 1996 arcade version. There are also PC versions released by the Japanese publisher Unbalance. All of the games in the series are available in Japanese only. The latest chapter in the series was released on June 15, 2011 for Apple iOS devices. Based on the 1996 arcade game, Densha de Go! was one of the first commercial train-driving simulation games, and went on to spawn numerous successors. The player can choose from a variety of tracks and trains and will then have to drive the train to the designated stations while sticking to the tight schedule, stopping exactly at the marked positions, obeying all signs and signals, and ensuring passenger safety and comfort.
