[Harry Potter] Why is the conductor of the Hogwarts Express almost never mentioned by anybody?

In the Prisoner of Azkaban, after the dementor incident, Lupin goes to have a "word with the driver." As far as I can tell, he's not mentioned before or since.

Who the hell is this guy? The Express is likely a powerfully magical object, capable of entering and leaving pocket dimensions (Platform Nine and Three-Quarters), obscuring its seemingly obvious route from Muggle eyes, and who knows what else. The man in charge of all this is clearly a remarkable wizard; so why does he get so little mention?

I doubt he's the guy that's responsible for all the magic. Likely, Dumbledore or whoever was headmaster at the time placed all the charms and spells on the express and the platform, and this guy, who could even be a squib, just drives it.
