The invention is directed to an improvenient in tie plates. Tie'plates are ordinarily" forrned with the edges beveled, the bevel flarof the notch so worn is deterrninedby the bottom edge of the tie which; presents a coI n-v paratively sharp edge tov the i Wall thus by the notch worn into the tie. Features and details of the invention will appear from the.

, specification'and claim.

A preferredr embodiinent of the invention. is illustrated in the acco npanylng' drawings.

1 marks the rails and 2 the ties of the track. 7 A tie plate is providedwith a continuous V hooked rib 4 adapted to hook over one'edge of the rail flange. Preferably the undersurface *of the hooked encl of the rib has clearance I from the upper surface-.of'the flangegper I initting a'slightmovementof the rail up and]. down, relatively to the hooked edge, this yielding assisting in preventing the movement of the tie plate on thetie.

i A rib 6 is arran'gedon the tie plate and]; 1 I engages the opposite edge ofjtherail flange l from that of the rib 4." Spike openings 7 are r forined in the plate, the inner wall'of each spike opening being flush with the inner s1ir- "I I .face of the shoulderfi, 'This preventsthe; I driving of the; spike in a manner that the i I inner surface of the-spike Will be in'rulobing, engagement with the edge of the rail, the we v inner wall of the opening-7 holding the spike 7' I --freefromsuch'rubbing engage nt, f I I V Spike bracing shoulders Sextnd upwardly i I fromthe plate, the inner fao e of thes eishouli r 'being s fl-withj h other-wallsof the 'Jon vize.
