Three different types of concrete track bed were designed and built. Results of tests of rail deflections, both vertical and lateral, under dynamic loading are given and shown on charts. The static vertical deflections of the three types of track beds are compared with that of the standard tie and ballast road bed, over a period of 19 months service. The economics of the concrete railway road bed indicate that the cost reflects about an 18% increase over the standard tie and ballast structure. A comparison of the vertical and lateral accelerations of a locomotive and car, measured at the start of the tests over the concrete bed track structure and 8 months later show no marked change in their values over the 8 month period. The uniform and small settling did not increase beyond the initial values. Good riding quality of the trains passing over these sections at 200 km/h continued throughout the test. The shelling damage to the rail laid on the concrete rail bed is not higher than on the conventional track structure.
