It is obvious that such a continuous contact could notbe obtained by the most laborious machining or milling of thosesurfaces. The adhesion of the molten zinc to the rails andplates, together with the body-bound rivets, hold the joint per-manently tight, and at the same time prevent expansion, thus making the rails continuous. The method of constructing thejoint is as follows: After the material has been distributedand the rails placed on ties, but before the latter are spiked,both plates and rails are thoroughly cleaned by a portable sandblast. The plates are next placed on the rail ends and heldin place by steel drift-pins, placed one in each end of the plate.
