In the world I'm building, there is a steam-powered train, but it's a steam turbine locomotive, not a steam piston locomotive. Otherwise, the desired technological level of the world is (more or less) generally that of Medieval Europe, plus magic.
My question is: what are the larger implications of a steam engine in the world? Is it possible for there to be a steam turbine locomotive without a larger industrial revolution, so as to maintain the otherwise-Medieval setting?
Edit: I've been asked to make this question more specific, so let me rephrase it: Would it be plausible for the steam engine in my world to be applied in transportation (trains, steamboats, etc) but not in the production of goods (triggering larger factories, mass production, etc)?
Edit 2: Based on the responses, it seems more realistic that the train in question would be piston-powered, not turbine powered, so we'll go with that. Going back to the question though, if not for technological reasons, Could there be some plausible cultural reason preventing steam-powered factories? Perhaps an extremely strong guild of artisans that has similar objections to steam-powered industry as some modern labor unions have to automation? Or some other reason?
Edit 3: This thread can be closed. My solve is that while the steam engine exists in my world, coal does not (based on some of the explanations in this thread), and there are cultural and economic reasons why wood can not be supplied in sufficient quantities to power steam engines on a wide scale. Therefore, heating the steam engine relies on magic, which is is less reliably accessible, and thus while the technology exists, steam engines are relatively rare.
