Summary	In the single-track railway lines, the stopping station type and the train series of Taiwan Railway Administration (TRA) Taitung Line (Hualien-Taitung) is the most complicated one. Due to the trip type of the passengers on this line is more particular than other railway lines; the number of trains on the schedule is extremely different between weekdays and weekends (or holidays). In current issues, in order to increase the volume of the TRA Taitung Line, increased to double-track for all of this line has been mentioned. But the TRA has done a perfect train timetable for the extra trains on the Taitung Line to prevent the scheduling problem when the extra trains joined in the diagram? In this situation, can we just fix the train timetable to have a perfect diagram on the single-track railway line, do the partial double-tracks works, or increase the stations to have the train-meetings, to prove the extra train’s schedule problems and increase the level of service of the TRA Taitung Line. The study is going to figure out the key point problem of the TRA Taitung Line, and to investigate doing the train schedule pre-defaulted for this line in order to let the diagram runs more efficient. Furthermore, the study will point out can we just do the train scheduling well, or construct the partial double-track and increase the stations to have the train-meetings; to avoid to all TRA Taitung Line has double-tracked. At last, the study can also suggest the situations have found in the study to Taiwan Railway Administration, for the new ways in order to do well works on the train scheduling for the single-rail line, or to release the bottlenecks for train scheduling on TRA Taitung Line. The mathematical programming is used in this study, and the object function is tend to balance minimize the train running time and maximum the volume of this railway line. The restriction functions would use the functions in the paper reference and restriction functions of the single-rail system to do the train scheduling. By the way, some restriction functions are too complex to appear the well train schedule. Therefore, these restriction functions are going to solve by handworks to make the train schedule to practice the better mode. The train schedules are difference to the weekday’s timetable and the holiday’s timetable, in order to let the TRA Taitung Line operate in the smooth and better situation. The conclusion of the study could appear that the train schedule of TRA Taitung Line could operate as a limited-express train, a semi-express train, and a local train in an hour between 6 a.m. to 10 p.m., which runs more train trips in the current railway line situation. Even though some trains’ operation time will be extended some running time, we can not only put in more running trains, but also we can figure out the bottleneck single-rail sections of TRA Taitung Line. If we do some works on these bottleneck raiway line sections, double-rail or station-improve as the examples, could be enhanced the train running status, the operating efficiencies of timetable, and the temporary train scheduling space.
