Jack, Maria, Bill, and Emily were normal railroad workers with normal lives until one day while hauling a freight, their train slips through a portal and ends up in Equestria, but now a group from their world called the United Galaxy Defense Alliance has launched a search rescue team to look for them, hilarity ensues as the crews try to figure out how to get back to their own world and the search and rescue team try to get to them.
