What our club has always done is to record two sets of LRUD data for 
any continuing station - a set perpendicular to the incoming leg and a 
set perpendicular to the outgoing leg.  We record one set for beginning 
and one set for dead end stations.  This gives us a lot of information 
about the shape of corners in passages.  Junction points wind up with 
more than two sets of LRUD - even better for specifying chambers, etc.
