Answer 1

I think that one of the reasons as to why steam power in boats and trains were at a disadvantage is that they’re big and heavy, expensive to maintain (increased costs) and i’m not quite sure about the second option but I think that maybe it may lead to more accidents? (they all seem quite likely)
