FIELD: designs of track structure. SUBSTANCE: track structure has wooden tie with upper bed and tie plate installed on it. Each tie face oriented along tie projects in horizontal direction beyond upper bed. Tie bed under tie plate rises with respect to tie surface beyond tie plate. Installed under tie plate is shock absorbing pad with projections directed downward over perimeter. Tie upper bed rises under tie plate due to depression made near each end of tie plate oriented across the tie on tie upper bed, or due to fastening to plate upper bed in zone of tie plate of additional plate. Tie plate lower bed has recesses. EFFECT: higher reliability due to prevention of penetration of atmospheric moisture. 8 cl, 11 dwgi
