[2] The overall design proposed by Ansaldo STS is related to the whole ETCS L2 equipment.安萨尔多STS建议的总体设计与整个ETCS L2设备有关。

1.1Line description:线路说明[3] The overall design includes 10 station: New XingYang, New GongYi, LuoYang Nan, New MianChi,New SanMenXia, New LinBao, New HuanShan, New WeiNan, New LinTong, Xi’An North.总体设计包括10个车站：新荥阳，新巩义，洛阳南，新渑池，新三门峡，新灵宝，新郇山，新渭南，新临潼，西安北。

[4] The overall design includes 25 CAI for the actual coverage and an additional CAI for the extendedcoverage foreseen in the future.总体设计包括将来预期扩展的覆盖范围的实际覆盖的25个CAI 和其它CAI。

[5] The line is composed by two parallel tracks. 线路由两个并行的轨道组成。

[6] There are three branch lines: one starting from station New Xing Yang, one starting from NewLintong and one starting from Xi’An North. 有三条支线：一条从新荥阳站开始，一条从新临潼站开始，第三条从西安北站开始。

[8] In the following figure is represented the whole line:下图显示的是整条线路。

[12] Each RBC can manage up to 30 train at the same time due to the limitation of the Radio Channel.由于无线电信道的限制，每套RBC都可以同时管理多达30列列车。

[13] Is possible to manage two handovers at the same time for each RBC (each train moving from oneRBC area to the next one uses an additional channel); this implies that the channels to be considered at any time are 28.如果每套RBC（每列列车从一个RBC覆盖区域移动到下一个RBC覆盖区域采用额外的通道）可能同时管理两次切换吗，这意味着需要同时考虑的信道数为28个。

[14] 对于郑西线而言，一个车站的侧线数量不超过18个；In ZhengXi line a single station has no more than 18 sidings.[15] The design speed is 350 km/h in the nominal direction. The minimum distance between two trains atthis speed is 14 km.在正常方向上，设计的车速为350千米/小时，在设计车速下，两列列车之间的最小车距为14千米。

[16] The operating speed is 300 km/h in the nominal direction. The minimum distance between two trainsat this speed is 12 km. 在正常方向上，列车的运行速度为300千米/小时，在该车速下，两列列车之间的最小车距为12千米。

[17] Average speed of 300 km/h implies that the number of trains along the line could raise up to 133 inthe nominal condition.300千米/小时的平均速度意味着沿着该条线路正常方向上的列车的数量可以上升到133列。

[18] A worse case for designing the number of RBC is to suppose that trains run at a maximum speed of300 km/h with a maximum MA length of 12 km, instead of 14 km. This situation forces RBC to manage more trains than the scenario with 350 km/h.设计上RBC数量最不利情况是假定列车在最高车速300千米/小时，最长移动授权距离12千米，而非14千米。

这种情况下将迫使RBC 管理比350千米/小时情况下更多的列车。

[19] There are no constraints on defining the borders of RBCs with only one exception: the border mustcoincide with the border between two block sections.除了一种例外情况，对RBC的边界定义没有限制：边界必须与两个闭塞区间之间的边界一致。

[20] For each block section are foreseen three balises.预期每个闭塞区间有三个应答器。

[21] For the design of the line was taken into account the nominal condition of the line as follows for eachtrack.线路的设计应考虑下述每条轨道的正常条件。

[21.1] In the nominal condition, there is one train connected with a RBC via one radio channel foreach siding of each station included in the line.在正常条件下，线路上每座车站的每条侧线都有有一列列车通过无线电信道与RBC相连。

[21.2] In the nominal condition, in line there is one train every 12 km connected with one or twoRBC (in case of handover) and running at 300 km/h.在正常条件下，线路上每12千米有一列列车与一个或两个RBC（当切换时）相连并在300千米/小时速度下运行。

[21.3] For each branch line there is one train connected to a RBC.对于每个支线，都有一列列车与RBC相连。

[21.4] It’s supposed that at most 13 trains per station are connected to an RBC假定每座车站最多有13列列车与RBC相连。

2.1其它说明Further Remarks[22] ERTMS 2级和CTCS2共享应答器的可能性应在详细设计阶段进行检验。

The possibility of sharing the ERTMS L2 Eurobalise with CTCS2 ones shall be verified in the detailed design phase.3LINE Design线路设计[23] According to assumptions described in chapter 2 the resulting number of RBC is 5根据第二节中的假设情况，最终的RBC数量为5套。
