目前全路无线列调制式主要有B和C 2种,设备改造中各铁路局大多以路局为单位,选择不同的无线列调制式。随着铁路改革的深入,尤其是撤消分局和开行长交路列车后,对原有列车调度区段进行了重新规划,原先以路局为单位相对独立的制式体系被彻底打乱。
At present, there are mainly B and C types of wireless column modulation in the whole road. Most railway bureaus in the transformation of the equipment take the road bureau as a unit and choose different wireless modulation systems. With the deepening of the railway reform, especially the withdrawal of sub-branches and the governor to cross the train, the original train dispatching section has been re-planned, the original road bureau as a unit of relatively independent system was completely disrupted.
