Main and Diverging Routes

Which route is which?

The 'straighter lineup'

The track number doesn't change?

The Train Operator must know what signal to accept at each interlocking.

Well, it varies:

LINE	STATION	DIRECTION	MAIN (G/G)	DIVERGING (G/Y)
F	West 4th	South	Take switch to left and stay on track B1	Straight line into track AB1
F	North of Bergen	South	Straight into lower level B1 to B3 track	Right hand switch staying on B1 to upper level
Q	Atlantic	North	To tunnel track in DeKalb A4 to B2	To bridge track in DeKalb A4 to A4
R	South of DeKalb	North	To bridge track in DeKalb F2 to A4	To tunnel track in DeKalb F2 to B2
Pitty the train operator who runs the Q and R on different days!
