Decision variables.

Symbol	Description
	0-1 binary routing variables, , if train used the link at some time. Otherwise,
	Arrival time of train on link
	Departure time of train on link
	0-1 binary train ordering variables, , if train arrive at link after train . Otherwise,
	0-1 binary stopping plan modifying variables, , if the stopping plan of train at the destination station of passenger OD pair modified from passing through to stopping. Otherwise, ,
	0-1 binary inserting variables, , if train is inserted. Otherwise, , and
	0-1 binary train delay variables, , if train arrive at destination later than the predetermined arrival time. Otherwise, ,
	0-1 binary passenger to train assignment variables, , if passenger OD pair takes train to finish its trip. Otherwise,
	Volume of passenger OD pair transporting by train to finish its trip
