HYDROKINETIC BRAKES ON THE PROTOTYPE APT

To keep within the braking distance allowed by existing signaling, British Rail's three prototype advanced passenger trains (APT-P) are being equipped with a novel form of hydrokinetic brake based on the same principle as the fluid coupling. Braking energy heats water which is cooled in radiators after each stop is completed, thus allowing service braking from 200 km/h to be repeated at frequent intervals. Without the HK brake, articulation of APT-P trailer sets might have proved impractical because of the high loading on non-powered axles which cannot be braked electrically.
