Sekai Projectreleased the original game for PC globally via Steam in June 2018. The company describes the game's story:
Maitetsu takes place in an alternate reality in Japan, where railroads were the most popular form of travel and transportation. But the difference with these railways is that the trains were paired up with humanoid modules called “Railords.” Due to a popular new form of travel, the railroads were practically forgotten about and eventually, railways were discontinued.
Players will assume the role of Sotetsu, a recent high school graduate who, shortly after entering University, decides to return to his adoptive hometown to save it from water pollution caused by the proliferation of factories. By chance, Sotetsu reawakens “Hachiroku,” a recently decommissioned Railord. He becomes her owner and decides to assist her in finding her missing locomotive, the “8620,” while attempting to save his hometown in the process.
