调车场箭翎线的运营效果及其适用范围

WORKING EFFECT AND SCOPE OF APPLICATION OF HERRINGBONE TRACK IN SHUNTING YARD

针对采用箭翎线调车作业方式所产生的编组节省，提出在我国调车场设置箭翎线的有利性以及地区车流量的适用范围。研究结果表明，若在主调车场设一组单向贯通式箭翎线，几个方向摘挂列车共用，当主驼峰解体照顾编组程度为０．５，每编组一辆车所增收的纯利润为其成本的１０％，投资还本期分别取１０、２０年，则地区车流量分别大于２５７、１３３辆／日时经济上有利。

In this paper, the advantage of setting-up herringbone track in shunting yard andits suitable regional wagon flows are presented according to the saving of marshalling localtrain that is produced by the type of the shunting work of the herringbone track. Supposingthat a single through herringbone track is set up in the main shunting yard and shared by local trains of several directions,when the level of main hump sorting considering marshallingis 0.5,the pure profit increased by marshalling a wagon is 10%of its cost.As the year of repayment of investment are separately 10 and 20 years,the result shows that when regionalwagon flows are separately bigger than 257 and 133 wagons every day,it is beneficial on economy.
