BNSF Timetable Questions

I have two questions to help in the deciphering of BNSF ETT's. First, does anyone have the index for the Rule 4.3 Station Type codes? Specifically X,B,J,M,Y and T. Second, how are tracks numbered in places where there are more than one Main Track. Specifically across the BNSF Northern Transcon and Scenic Sub into Seattle. Thanks.

On the triple-track Chicago sub, tracks are numbered 1 to 3 north to south. I'd imagine the northern Transcon and Scenic sub follows the same pattern...

On east-west tracks they number them so when facing east (traffic wise not necessary the real direction) the left hand track is 1, then 2, 3 and 4 if needed. Guess it could go higher than 4 as well but I don't know if anywhere has more than 4 mains, only place I've seen 4 is out on the Orin Sub in Wyoming.
