TRAFFIC IN A CURVE WITH RAILWAY COACHES FITTED WITH INCLINABLE BODIES

Further tests of the pendular type coach have been effected, during which the body has been given a boost to speed up the time taken for it to get the correct inclination when negotiating connecting transition. This is done by means of a hydraulic ram monitored by a accelerometer detecting, permanently, the non-compensated acceleration. Another arrangement is being worked out with a coach for which the axis of oscillation is below the center of inertia of the body. Tests are described which show that it is possible to get a coach to negotiate a curve with 0.3 insufficient cant, which is considerable, by employing assisted pendular motion. The first tests have shown that the assisted pendular motion gives considerably improved smooth riding while negotiating the transition as compared with natural pendular motion.
