I started developing this idea of an Undertale AU where everyone is a staff member of a railway station 🚉. These trains connect the Undertale Fandom to the Internet in which, to be more specific, is the other fandoms such as FNAF fandom, BATIM fandom and CRK fandom. As long as the station exists the Undertale multiverses will still be connected to the Internet and not forgotten. It's hard assigning roles to each character but I will try my best. I named this AU Under Express - Undertale express. Also, here are Under Express! Frisk, Chara and Asriel.
