The only Railgun novels are two side stories that have Mikoto unknowingly taking on magic side antagonists. If you're asking about if Index and Railgun are the same no, they tell the story of events in Academy City from completely different perspectives. While Railgun shows use how Mikoto learned about the Level 6 Shift experiment it doesn't rely on retelling the same arcs with Mikoto again and has instead focused on telling original stories, featuring Mikoto and her friends at the center of them.
