Bearing of the Rail on the TieThe general tendency at the present time is more and more towards the use oftie plates. With the introduction of the treated tie it is necessary to adopt somemeans to protect the wood from wear at the rail bearing on account of the longerlife of the tie. The objections which have been made to tie plates were, first of all, thatthey buckled severely. This, however, has taken place only when the plates were too thin, and thefollowing record of testsmade of a prominentmake of tie plate showthat the present plateshave ample strength toresist buckhng (TableXXIII and Fig. 85). Most plates havebeen made with the ideaof being anchored to thetie so as to prevent thecommunication of themotion of the rail to the plate. As a result, we have a large number of differentforms of plates, provided with prongs, spines, or flanges on the bottom, which are pressed into the tie either by table xxiii.—test of McKEE tie platethe weight of the passing l
