An "ABI" track section provides following Interface (SrrTrackSectionA)
A 30° turnout provides following Interface (SrrTurnout[Left|Right]A)
The "ABI" track geometry uses SRR objects to realize the SRR railway kinematics, those SRR objects are described here.
You could provide your own track geometry - please have a look into the "how to build my own tracks and turnouts" document (English/German).
