In 1912 there were about sixty Kimball ties in successfuluse in the track of the Chicago and Alton Railroad, the ties having been installedin 1905. Percival Concrete Tie. — (Fig. 70.) The figure shows ties which wereused on the Pittsburg and Lake Erie Railroad for about two years. They were 102 STEEL RAILS removed from the track in 1908 for the reason that the ties failed. The figureillustrates very plainly how and where these ties failed.
