To save the man power and material resources and for the convenient of railway traffic control, regional computer interlocking will be implemented to the Frontier inspection yard, 西伯库仑 Station and 30km Station. Centralized control will be realized in 西伯库仑 Station. If required, the control right can be decentralized for independent control. Independent control is adopted to Nariin Sukhait Station due to its busy operations.
② 显示控制方式：Display Control Mode:
均采用CRT显示器终端+鼠标控制方式。 CRT monitor terminal plus mouse
③ 信号机：Signal:
各站信号机均采用透镜式色灯信号机，各站进站、正线出站及预告等列车信号机，以及专用线、牵出线入口等处联锁区的调车信号机原则上设高柱信号机，其它信号机设矮型信号机，高柱信号机机构均采用铝合金机构。
Lens color light signal is adopted at stations; in principle, high post signal is adopted for home signal, exit signal at main line and distant signal and shunting signal at inter-locking zone at entrances of feeder line and pulling-out line. Other signals adopts ground signals and high signals adopts A-alloy structure.

④ 轨道电路：Rail Circuit:
全线各站轨道电路均采用97型25Hz相敏轨道电路。
25Hz phase-sensitive circuit type 97 is adopted for rail circuit of all stations along the whole line.
⑤ 转辙设备：Switch Equipment:
转辙机类型：50kg/m12号和60kg/m道岔采用ZD6-E/J型电动转辙机，其它道岔采用ZD6-D型电动转辙机。
Model 50kg/m #12 and 60kg/m switches adopt ZD6-E/J electric goat and other ZD6-D.
根据运基信号〔2004〕182号文要求，为了提高电务检修能力，道岔设置转辙机表示缺口监测报警装置，并纳入计算机监测系统统一管理。
According to Document YJXH [2004] No.182, goats with gap-monitoring alarm are set at railway switches and integrated into the computerized monitoring system for unified management to improve the ability to check and repair electric faults.
⑥ 电源设备：Power Equipment:
西伯库仑站和那林苏海特站采用大站智能型综合电源屏，边检场站和30公里站采用小站智能型综合电源屏，（含25周轨道、电码化电源）。供联锁设备、电码化及计算机监测设备、TDCS车站分机用电，智能型综合电源屏的监测报警信息纳入计算机监测系统统一管理。
Large station intelligent integrated power screen is adopted to 西伯库仑 Station and Nariin Sukhait Station. Small station intelligent integrated power screen is adopted to frontier inspection station yard and 30km Station, (including 25 tracks and coding power supply). It will supply power to inter-locking equipment, coding and computerized monitoring equipment, TDCS station extension and monitoring and alarm information of the display will be integrated into the computerized monitoring system for centralized management.
⑦ 电线路：Electric Circuit:
由于预留了电气化条件,电线路干线电缆采用PTYL23型铝护套综合扭绞信号电缆，其余分支电缆采用PTYA23型综合护套扭绞信号电缆。
Due to reservation of electric conditions, main cable for electric circuit adopts PTYL23 aluminum jacket comprehensive twisted signal cable and other distributing cable adopt PTYA comprehensive jacket twisted signal cable.
车站干线电缆采用电缆槽进行防护。干线电缆石质地段、桥上电缆均设电缆槽防护，过小桥、涵及道口采用钢管或槽钢防护。
Station main cable is protected by the building of cable tanks.  Cable troughs are set for the protection of main line cables in stone sections and for cables on bridges. Steel tube or channel steel is set for the protection of cables while passing small bridges, culverts and crossings.
⑧ 列车运行安全防护：Train Operation Safety Protection:
站内正线正方向接发车进路电码化采用预叠加发码方式，侧线股道采用叠加电码化方式。发码设备均采用ZPW-2000发码设备。
Advance overlay signaling is adopted for coding of forward reception and departure routes for in-station main line. Signaling equipment adopts ZPW-2000 signaling equipment.
