It depends on what context you put it in. They'll have a list of places where it is to go and Swindon may not be on it. Doesn't mean it will never pass through sometime in the future.
For everything else like maintenance, etc it's entirely up to them and the worlds foibles. I don't think they're inexperienced. They've managed to raise millions to build a steam locomotive. I don't see much of the teenage rail froth managing to get out of bed, never mind build a steam locomotive. :roll:
