ENGINEERING AND ECONOMIC ANALYSES OF WOOD TIE-VS. CONCRETE TIE TACK

Engineering and economic studies were conducted to determine the conditions under which concrete cross ties would be justified. In the process of comparing wood and concrete ties the following factors influence the outcome: (a) in-place cost of ties, (b) service life of ties, (c) service life of rail, (d) cost of rail renewal, (e) tie spacing. The investigation of engineering aspects has been confined to the effect of tie spacing on the track stability, with particular attention to the allowable increase of spacing when concrete ties of selected types (MR-2 and B-58) are used instead of wood ties. For a realistic evaluation of the economics of wooden ties vs. concrete ties, the discounted differential cash flow method was applied.
