Abstract (en)
[origin: US4381076A] The construction of steel-concrete railroad ties onto which rails are fixed is disclosed. The ties are composed of a metal saddle for fastening to the rail, comprising a tie-plate extending over a part of the upper surface of the tie and forming the zone for attachment and support of the rail. The tie-plate further extends into the tie through ribs sealed in the concrete of the tie and constitutes at least part of its reinforcement.
