Operations control system in the Lotschberg Base Tunnel

摘要

The new Lotschberg Base Tunnel, which is partially single-track, is equipped with its own operations control system, called AF (Automatic Function). The AF system solves operational conflicts automatically or with the intervention of the dispatcher, according to situation. Switzerland's railway companies probably operate the world's most complex railway network. There is a highly ambitious timetable, the so-called "Taktfahrplan", with regular intervals and extremely dense traffic at the major rail network nodes. Almost all the main lines are used for both passenger and freight trains. Train operations are controlled by a centralized and fully automatic system based on the given schedule and a train identifier for each train. Most interlockings are controlled remotely from the central control system (system ILTIS by Siemens).
