DB EXPERIMENTS WITH POWERED TILTING OF COACH BODIES

A three-car diesel train with air suspension has undergone field testing to develop an electro-pneumatic servo which tilts the body inward on curves. The three-car diesel train has been run experimentally at 130 km/h over a route that is largely limited to 105 km/h. If the train itself was capable of higher speeds it is claimed that 135 km/h could have been attained safely. Air springing provides the tilting mechanism, the servo system being arranged so that the air bellows on the outside of the curve are inflated and those on the inside deflated, thus tilting the body relative to the bogie towards the inside of the curve. The centrifugal force that can be tolerated without discomfort is taken as 0.067 g, which is equivalent to a cant deficiency of 100 mm.
