It's actually even smaller than that. The Anglia is pretty close to HO scale. Would scale well with the HO or OO Hogwarts Express. Grabbed it a couple months ago for my HO layout.
Looks like my post got deleted (mabye for having links in it) but suffice it to say I also picked up the wave 3 figure set recently.
Going to get Wave 4 set soon. Looks like there's some good figs in there.
