Cc = Car Capacity
SCc = YCc + Icc = Storage Capacity
YCc = Yard Car Capacity
ICc = Industrial Car Capacity
FCc = functional Car Capacity
MLPCc = Mainline Passing Track Car Capacity
NCM = Average Number of Cars Moved/Operating Night
Cis = Cars in service
SS = Storage Saturation
--->A = ideal = 80-85%
--------SS = Cis/SCc x 100
FS = Functional Saturation
-->B = ideal 40-50%
--------FS = NCM/FCc x 100
ITCcE = Intransit Car Capacity Eastbound
ITCcW = Intransit Car Capacity Westbound
Functional Mainline Saturation
--->C = ideal = 25-35%
FMLS = ITCc x (E or W)/MLPc x 100
