Centralised Traffic Control Centres (CTC)

摘要

This paper describes the computerised CTC's developed by Alcatel for the Portuguese Railways. The system is the last generation of Centralised Traffic Control Centres and is based on the concept of high-availability and safety. These CTC's are currently being installed in a increasing number of locations where they control the signalling of different types of lines: single track (Beira Alta line), double track (North line) and suburban (Sintra line, the line with the most n~o of passengers per day in Europe). These CTC control Alcatel electronic interlockings ESTW L90.
