Problem with point of origin of Func_train

[htman]

Hello. (and sorry for my bad English) Can you help, plz? I have problem with strange location in Func_train brushes.
Func wrong determines the point of origin of train brushes. But it should work properly. 
This problem has not disappeared even after using different compilers. (btw i use GTKRadiant 1.5.0)
Else func_train of models work properly. (cuz point already included).

Here to example .bsp with that bug and .map .

Quake2's func_train doesn't use its origin brush to follow path corners, but rather the lowest corner on each axis minus 1 (bottom southwest corner). This is because most brush models in Q2 aren't required to have origin brushes, only ones that rotate.

That said, KMQuake2 does support a func_train_origin variant that behaves like the ones in other games.
