Futuron was a subtheme of Space released in 1987. Like all good themes, this one had to end eventually, as it did in 1990. The theme was based off the "everyday lives" of astronauts. Last time I checked, astronauts don't get to ride trains in space...
The idea of the theme was that the Futuron people would walk around and enjoy their lives.
