Automatic train protection

Automatic train protection (ATP) is a type of train protection system which continually checks that the speed of a train is compatible with the permitted speed allowed by signalling, including automatic stop at certain signal aspects. If it is not, ATP activates an emergency brake to stop the train.[1] ATP systems are now a legacy, defunct technology that has been superseded throughout Europe and internationally by the European Rail Traffic Management System.[2]

The staggered deployment of the current ATP system is shown in Figure 2. The railway automation industry will not continue to support their old product families indefinitely. As the life cycle of the ATP system is coming to an end, there is no choice but to migrate to the ERTMS/ETCS, even if the new system is not necessarily an improvement...
