在索非亚—普罗夫迪夫156km铁路复线上安装的先进的调度集中设备于1987年7月竣工。它是保加利亚国营铁路最繁忙的线路,除连接索非亚和普罗夫迪夫两个重要工业城市外,已成为连接欧洲各国和土耳其之间直通铁路的一部分。这条铁路早已实现双线,并提高了25kv供电容量,用调度集中设备完成自动化系统的远距离控制,以后还将在机车上采用由微处理机构成的列车自动控制系统和列车无线电话,全部信号和通信设备现代化包括平交道口自动化和线路两端大型编组站自动化。
The state-of-the-art dispatch center installed on the 156 km railroad double track in Sofia-Plovdiv was completed in July 1987. It is the busiest route for the Bulgarian State Railway and, apart from linking the two major industrial cities of Sofia and Plovdiv, has become part of the direct link between Europe and Turkey. The railway has already achieved double-line, and increased 25kv power supply capacity, using centralized equipment to complete the automation system long-distance control, will also be used in the locomotive by the train control system consisting of train and train wireless telephone, all Modernization of signaling and communications equipment includes crossing automation and large marshalling station automation at both ends of the line.
