CUSHIONED CONCRETE TIES FOR ULTRA-SMOOTH TRAINS

A NEW TRACK DESIGN MADE OF CONTINUOUS WELDED RAIL, SECURED ON CUSHONED CONCRETE CROSSTIES BY ELASTIC SPRING FASTENERS, IS EXPECTED TO PROVIDE COMUTERS WITH A WHISPER SMOOTH TRAIN RIDE. THE CONCRETE CROSSTIES HAVE ALREADY WON SIGNIFICANT APPROVAL IN EUROPE AS AN ECONOMICAL, HIGHLY EFFECTIVE WAY TO CONVERT AN ORDINARY RAILROAD INTO A HIGH SPEED RAILWAY SYSTEM. THE CROSSTIES RESEMBLE BARBELLS MADE UP OF TWO CONCRETE BLOCKS CONNECTED BY A STEEL TIEBAR. SECONDARY REINFORCEMENT CONSISTS TOP AND BOTTOM LONGITUDINAL GRIDS THAT CONTAIN TEN REINFORCING BARS AND A ROUND SPIRAL CAGE. THE NEW DESIGN PROVIDES A TRACK THAT HAS 97% FEWER JOINTS AND ONE THAT WILL LAST 33% LONGER THAN CONVENTIONAL TRACK. MAINTENANCE COSTS ARE REDUCED BY ABOUT 50% PER TRACK MILE.
