"LRC" PROTOTYPE DEMONSTRATED--POWERED BANKING ON CURVES IS KEY FEATURE ON NEW CANADIAN FAST-TRAIN CAR

The prototype coach of Canada's high-speed "LRC" train has successfully undergone running tests at speeds in excess of 90 mph. When completed, the "Lightweight Rapid Comfortable" train would operate in pushpull service, with a locomotive at each end and up to 12 coaches, at speeds up to 120 mph on existing North American Tracks. LRC's most significant engineering feature is its "powered banking" system, built into the car suspension. The two-axle trucks, are basically of conventional design, but they have an additional bolster that can tilt the car body to compensate for up to 10 deg of unbalanced superelevation. Each truck has a sensor, which responds to centrifugal force and seeks a bank angle that will reduce this force on the passengers to near-equilibrium. The sensor activates a servo mechanism that causes the banking bolster to be rotated hydraulically until the car body meets the desired bank angle.
