We've more or less asserted why the Hogwart's express exists, but at some point in Hogwarts history it didn't. No problem I though, everyone just apparated with their children to Hogsmeade,
no problem a long and tedious process considering luggage, and number of children. Except then I realised, how would a muggleborn student get there?
I'm assuming that despite the era (witch burning etc.) that the founders were actively recruiting and not just leaving students too far south from Hogwart's to grow up untrained. So how did they get the students to Hogwart's?
