CNR SETS POLICY ON USE OF CONCRETE TIES

Canadian National policy, at least for the next five years, calls for use of large numbers of concrete ties in curves, in existing main track in high-density, heavy- traffic territory. On curves of 4 degrees or more, these ties will permit rail to be transposed simply by removing and replacing the rail fastening clips. Wood tie life under heavy traffic has been shortened with gauge widening and rail overturning developing. Concrete tie used by CN conforms to British design, Type 23, but has more prestressing wires than the type which is standard on British railways.
