In order to meet the need of service speed of 350 km/h, train control system CTCS3 is applied in new passenger dedicated line. When GSM-R communication interrupts, CTCS3 depredates to CTCS2 to control the train. For the problem of high speed railway transport organization that GSM-R communication interrupts brings, we divides it into three influencing models, uses deduction method of correlates and direct computation method to analysis train carrying capacity, draws the conclusion that GSM-R communication interrupts can cause some influence to train speed and transport organization. The time of GSM-R communication interrupts (a certain period of time) estimates the area decreases obviously and the lower limit value of train carrying capacity, descripts that high speed railway transport organizations is often not carried out in accordance with the best transportation program.%针对GSM-R(GSM for railway)通信中断给高速铁路运输组织带来的问题,分3种影响模式,利用扣除系数法及直接计算法来分析列车通过能力,得出GSM-R通信中断对列车运行速度和运输组织造成一定的影响,GSM-R通信中断的时间(一定时间)测算列车通过能力的明显下降区域及下限值,说明高速铁路运输组织往往不是按照最佳运输方案进行的结论.
