2 兼容CTCS 2 Compatibility CTCS 2
为满足CTCS-2系统的动车组由既有线运行至高速线的需求，高速线列控系统应与CTCS-2系统兼容。
As to meet the requirements of dynamic group of CTCS-2 system from current railway to high speed line, the system of high speed line shall be compatible with CTCS2.
在高速线ETCS系统与CTCS-2系统的主要差异表现为地面系统为车载设备提供运行许可（目标距离、目标速度）信息的途径不同，ETCS系统是通过在每一个闭塞分区入口处（包括进、出站信号机）设置的有源应答器向列车传送ETCS /CTCS-L2报文的形式实现，而CTCS-2系统是通过轨道电路连续向列车传送列车运行前方空闲闭塞分区数量，根据轨道信息和应答器数据CTCS L2车载设备能够计算制动曲线相关的移动授权数据，两系统其余工作是基本相同的。额外的ETCS 功能对CTCS 2级系统来说是透明的，由于CTCS 系统忽略应答其中的ETCS专用数据。
The main difference between ETCS system and CTCS-2 system is the different approach to provide operating permission information (object distance, object speed) for ground system as well as equipment on the train. The implementation of ETCS system is to provide ETCS /CTCS-L2 message through the active balise which equipped on each block section entrance (including in-station signal, out-station signal). However, the implementation of CTCS-2 system is to provide the number of idle block sections in the direction of train running consistently to train through track circuit. According to track information and balise data, the CTCS L2 equipment on the train may calculate the moving authorization data related with braking curve. The rest of work of the two systems is the same. As to CTCS 2 level system the additional ETCS function is transparent due to the CTCS override to response the data specialized for ETCS system.
为满足3分钟运行间隔要求和与ETCS系统兼容，CTCS-2系统闭塞分区轨道电路设置与ETCS系统相同，采用ZPW-2000A轨道电路，轨道电路编码通过列控中心（TCC）进行直接控制，信息符合CTCS系统技术规范的要求。
To meet the requirements of 3 minutes interval for operating and compatible with ETCS system, CTCS-2 system is the same with ETCS system in the respect of the track circuit in block sections, which applied ZPW-2000A track circuit and the code of track circuit is directly controlled by train control centre（TCC）, information shall confirm to the requirements of CTCS system.
CTCS-2系统应答器设置与ETCS系统相同，通过在ETCS系统应答器中增设CTCS报文以满足CTCS-2系统的需要。在应答器报文中应答器链接、静态速度曲线（SSP）、线路坡度、特殊区段、级间转换、绝对停车和调车危险信息包是两系统共用信息。
The function of balise in CTCS-2 is the same with ETCS system. Requirements of CTCS-2 system are satisfied through adding the CTCS message in balise of ETCS system. The share information of two systems include balise link in balise message, SSP, railway slope, special section, level exchange, absolute shot down and shunting risk information.
3 备用系统 Backup system
客运专线列控系统采用ETCS-2级并兼容CTCS-2级的列控系统，当ETCS-2级系统车载设备、GSM-2通信系统、地面无线闭塞中心等设备故障时列车制动停车，经调度同意车载设备人工转换到CTCS-2系统，列车按CTCS-2系统继续运行。
故障导致CTCS-2系统也无法正常工作时，列车制动停车，按调度命令行车。
The train control system of passenger dedicated lines applies ETCS-2 system and compatible with the train control system of CTCS-2 level. When train is braking and stop due to the failure of equipments on train, GSM-2 communication system and ground wireless block centre, etc. Agreed by dispatching department, the equipment on train shall be switch to CTCS-2 system manually, and train operate under the system of CTCS-2.
When failure result the malfunction of CTCS-2 system, train shall be shut down and accept the arrangement of dispatching department.
