2 兼容CTCS 2  Compatibility CTCS 2
為滿足CTCS-2系統(tǒng)的動(dòng)車組由既有線運(yùn)行至高速線的需求，高速線列控系統(tǒng)應(yīng)與CTCS-2系統(tǒng)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.
在高速線ETCS系統(tǒng)與CTCS-2系統(tǒng)的主要差異表現(xiàn)為地面系統(tǒng)為車載設(shè)備提供運(yùn)行許可（目標(biāo)距離、目標(biāo)速度）信息的途徑不同，ETCS系統(tǒng)是通過在每一個(gè)閉塞分區(qū)入口處（包括進(jìn)、出站信號機(jī)）設(shè)置的有源應(yīng)答器向列車傳送ETCS /CTCS-L2報(bào)文的形式實(shí)現(xiàn)，而CTCS-2系統(tǒng)是通過軌道電路連續(xù)向列車傳送列車運(yùn)行前方空閑閉塞分區(qū)數(shù)量，根據(jù)軌道信息和應(yīng)答器數(shù)據(jù)CTCS L2車載設(shè)備能夠計(jì)算制動(dòng)曲線相關(guān)的移動(dòng)授權(quán)數(shù)據(jù)，兩系統(tǒng)其余工作是基本相同的。額外的ETCS 功能對CTCS 2級系統(tǒng)來說是透明的，由于CTCS 系統(tǒng)忽略應(yīng)答其中的ETCS專用數(shù)據(jù)。
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.          
為滿足3分鐘運(yùn)行間隔要求和與ETCS系統(tǒng)兼容，CTCS-2系統(tǒng)閉塞分區(qū)軌道電路設(shè)置與ETCS系統(tǒng)相同，采用ZPW-2000A軌道電路，軌道電路編碼通過列控中心（TCC）進(jìn)行直接控制，信息符合CTCS系統(tǒng)技術(shù)規(guī)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系統(tǒng)應(yīng)答器設(shè)置與ETCS系統(tǒng)相同，通過在ETCS系統(tǒng)應(yīng)答器中增設(shè)CTCS報(bào)文以滿足CTCS-2系統(tǒng)的需要。在應(yīng)答器報(bào)文中應(yīng)答器鏈接、靜態(tài)速度曲線（SSP）、線路坡度、特殊區(qū)段、級間轉(zhuǎn)換、絕對停車和調(diào)車危險(xiǎn)信息包是兩系統(tǒng)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 備用系統(tǒng) Backup system

故障導(dǎo)致CTCS-2系統(tǒng)也無法正常工作時(shí)，列車制動(dòng)停車，按調(diào)度命令行車。
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.
