In-cab signalling system. How it works - computer generated flythrough
This tried and tested system will replace traditional railway signals with a computer display inside every train cab, reducing the costs of maintaining the railway, improving performance and enhancing safety.
It will offer a host of benefits to the railway and the application of its cab signalling component, the European Train Control System, ETCS, will spell the end for traditional signalling.
Instead of lineside signals, a computer in the driver's cab controls the speed and movement of the train, whilst taking account of other trains on the railway.
By bringing the control system inside each individual train, ERTMS allows specific customised control. This allows the drivers to always run at the optimum safe speed helping more trains run faster and recover from delays quicker.
Installing ERTMS across the country as signalling becomes life-expired will save an estimated 40 per cent over conventional systems. Each train will run at an appropriate safe speed, allowing more trains onto the tracks. ERTMS will improve train performance and reduce energy consumption.
We're carrying out testing on part of the Hertford Loop, north of London, using a converted former passenger train. This will trial four suppliers’ technology and will help us decide which contractor is best suited to work with us installing ERTMS on the Great Western and East Coast Main Lines in Control Period 5 (2014-19).
Although still operating under the umbrella term of ERTMS, we're creating our own traffic management system to optimise performance.
