SIGNALLING THE NEW LYON LINE OF THE PARIS/SUB-EST NETWORK FOR 260 KM/H AND MORE

O Weber

Abstract

Because fixed-aspect trackside signalling is not applicable for speeds of 250/300 kph, continuous cab signalling will be applied to the SNCF high-speed line. Braking distances of 7000 m are accommodated in five or six block-section increments conforming to the speed- curve/gradient characteristics of the line. Emergency stops within 5000 m are achieved with magnetic track brakes. The line is to be in operation by 1981.
