Automation systems railways are achieving increasingly higher levels of automation. there are many features which affect railway safety and operating efficiency by means of better automation and improved signaling. there are many automation systems in operation around the world which perform such duties as remote interlocking, centralized control of traffic movement and automatic routing within a given interlocking section and often beyond. these, and many other tasks, allow a high degree of automated traffic flow. efficient and safe signalling is, of course, an integral part of these processes. modern, computer-based technology can greatly enhance these procedures by automating the decision-supporting process and so assist operations staff in their day-to-day duties. typically, these could include automatic train routing, initiation of information systems (for the traveling public as well as staff) and coordinating connections with other rail traffic sys-tems, such as suburban and regional services. added to this are further functions such as rolling stock dispatch, deployment of staff (both operational and maintenance), interactive changes of timetables and the automatic prevention of potential traffic conflicts. ответьте на вопросы в соответствии с содержанием текста. 1) what features affect railway safety and operating efficiency? 2) what duties do automation systems perform? 3) signalling is an integral part of automation processes, isn't it? 4) what technology can greatly enhance the procedures of automation systems? 5) what duties of operations staff do computer-based technologies facilitate?
