The use of reinforced-concrete ties on Soviet railroads favors the solution of an important national economic problem, the curtailment of the consumption of high-quality construction lumber. Experience gained in the operation of rail lines with reinforced-concrete ties has confirmed that the type now in use in the Soviet Union (prestressed, monoblock, piano-wire-reinforced concrete) in the majority of cases is of quite high strength and longevity. Tendency to damage and instances of removal from service are relatively low. Life of 2 to 3 times that of wooden ties is achieved. Another important advantage of concrete ties is their great resistance to shifting of the rail-tie system on the ballast; this facilitates the use of welded rails without seasonal stresses. However, the present high rigidity of tracks with reinforced-concrete ties does actually worsen interaction between train and track.
