The coach doesn't look big enough to have an engine within (when compared to the one used by railcars which takes all the front part), and the wheels don't look strong enough, at least not enough to support the chassis and motor. That said, train cars in Dunwall don't seem to have any engine at all, but they have the same reinforced chassis as railcars and rides on a different, electrified set of tracks. Speaking of which, I find it odd that this coach model isn't using any guiding rail, even inside the imperial estate! I would not ride on this if it was self-propelled, nor approach it while it's moving. Railcars are already unsafe enough for walkers and riders alike, why giving something unsafer to Dunwall Tower?

So yes I agree with you, I don't think they are self-propelled at all, it's just an assumption based on the absence of any horse model in-game. I can understand Arkane may not have the time nor the resources to create at least one.
