Interesting! I wonder why the Line strings blob differs... Maybe it doesn't represent bus stops at all, but points at which the route changes for the purpose of drawing?

It does seem to be "the route as you'd show on a map" - if I plot the two sets points on GPSVisualizer, it's fairly different.

I guess the 389/631 routes are reasonably simple and don't need more "drawing points" than you'd get from the bus stops anyway?

[edit: added the 389 bus stops and line points to the imgur gallery]
