Automatic train protection (ATP) is the generic term for train protection systems that continually check 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.{{Cite web|url=https://data.europa.eu/data/datasets/era-glossary-of-railway-terms?locale=en|title=ERA Glossary|website=ERA.Europa.eu|access-date=18 July 2023|url-status=live|archive-url=https://web.archive.org/web/20170506005106/http://www.era.europa.eu/Document-Register/Documents/Glossary%20of%20railway%20terminology-selection-%20EN-FR-DE.pdf.pdf|archive-date=6 May 2017}}
