贝加尔—黑龙江干线的工程特点是它大部分处于永冻地区,要经过数百公里难以通行的沼泽和冻土带森林。为了保证行车安全和区段最大通过能力,干线的自动装置应具有使用方便和高度的可靠性。苏联交通部召开了审查该线自动装置、遥控装置和通信的设计方案会议。会上提出了铁路运输通信信号勘测设计院的设计方案。它为下安加尔斯克分局提出了8个通信电路方案。它将建筑5～6层通信和检测站合用楼房,地上无人增音站将同客运用房或电气集中信号楼联结在一起。分局地区通信向全国通话可用铁路连接线,邮电部的通
The engineering features of the Baikal-Heilongjiang trunk line are that it is mostly in the Yongzong area, going through hundreds of kilometers of hard-to-reach marsh and tundra forests. In order to ensure traffic safety and the maximum capacity of the section, the trunk automatic device should be easy to use and highly reliable. The Ministry of Transport of the Soviet Union convened a meeting on the design scheme for reviewing the automatic devices, remote control devices and communications of the line. At the meeting put forward the design plan of railway transportation signal survey and design institute. It proposed eight communication circuit solutions for the Lower Angarsk Branch. It will be building a 5-6 floor communication and testing station with buildings, ground unattenuated stations will be used with the passenger or electrical centralized signal floor together. Branch regional communications available to the national railway lines, the Ministry of Posts and Telecommunications
