Like a lot of other young writers, I'm working with a fantasy setting. But, I should qualify that statement- there's no magic, and a moderate amount of technology seems more natural than the the typical medievalist simplicity in this world I'm using for a setting. Also, technically, I'm not using the whole "world"- only one continent, isolated (so far) and comprised of six different countries/empires. What I'd like to know is: Would the development and use of steam-powered trains before the discovery (and development) of gunpowder sound plausible enough to you? (A character does discover it in one story, but that's the idea- its a discovery and not just an innovation). Why or why not? Thanks!
