is a Japanese train simulation game series originally produced by Taito and more recently by Square Enix (who purchased Taito) and Railfan Holdings Co., Ltd. The series started with a 1996 arcade version and was first released in a home version for the PlayStation in 1997. There are also PC versions released by the Japanese publisher Unbalance. All of the games in the series are exclusively available in Japanese. Overview Each Densha de Go title contains actual train (or tram) routes based on real services in Japan. For the most part, the user's task is to drive the train and adhere to a very exacting timetable, including stopping at stations to within as little as 30 cm of a prescribed stopping point, ideally within half a second of the scheduled arrival time. While the specifics vary slightly between versions, generally speaking along the way, the user is expected to obey speed limits and other posted signs, sound a warning for work parties along the track, arrive at between-station waypoints on time, and perform similar tasks. Densha de Go differ from Ongakukan's Train Simulator series primarily in that while the Ongakukan series uses video taken from cameras mounted to the front of real-world trains for its graphics, Densha de Go titles rely upon computer-drawn graphics. History The 2004 title Densha de Go Final! was so named to signal that it was intended to be the last in the series. While still popular in an absolute numbers sense, the series had lost the novelty of its heyday while development costs for individual titles continued to climb due to the detailed virtual worlds that needed to be created. Taito and Ongakukan subsequently released a few co-produced titles for PlayStation 2, PlayStation Portable, PlayStation 3, and iOS with the title Railfan. Taito also divided the four routes in Densha de Go! Final into separate titles and released them on the PSP system. In April 2010, 5 years after Square Enix acquired Taito Corporation as a wholly owned subsidiary, Densha de Go! Special Version -- Revived! Showa Yamanote Line was announced for the Nintendo DS on July 22, 2010. This was a departure from the traditional publisher and distributor of Densha de Go, Taito. Densha de Go! Special Version—Revived! Showa Yamanote Line offers a variety of trains to control, from the early Yamanote Line up through the current rolling stock. Exclusive to the Nintendo DS,
