FLEXICOIL SECONDARY SUSPENSIONS IMPROVE HIGH SPEED RIDING

Following successful experiments with flexicoil secondary suspension fitted to a Class 86 electric locomotive, British Railways intends to make further use of this type of springing. Faulty hydraulic dampers caused pitching oscillations of 2.42 c/s resonant at 100 mile/hr with 60 ft. rail joints and body nosing oscillations of 1.25 c/s on straight track. Design installation and evaluation of a flexicoil suspension system resulted in significant improvement in the riding characteristics at high speed.
