At the ends of this longrail specially designed slip joints are used, where expansionis fully provided for. At Detroit, where a number of thesecomposite long rails are being tried, the center is anchoredby bedding several ties in a concrete foundation and slot-spiking the joint splices. At Saginaw, where more of theselong rails are being tried, the anchoring oi the center is ac-complished by bedding a 15-ft. vertical rail in concrete in ahole excavated in the roadbed. The top of tnis anchor railfits into a notch in the horizontal leg of a splice bar on thetrack rail. Mr. A. Torry, chief engineer, is conducting theseexperiments. 1B0 AMERICAN ENGINEER AND RAILROAD !«■—«#—•I Details of Cranes for Handling Trucks.
