A fiber-reinforced prestressed reinforced concrete sleeper is integrally cast and includes a sleeper body and two rail bearing regions. A rail clamping base is arranged on a surface of the each rail bearing region. The two rail bearing regions are located under rails on both sides of the sleeper and the two rail bearing regions are located above the sleeper body. A reinforcing fiber is mixed into the two rail bearing regions only, and a reinforcing rib is arranged in the sleeper body. The reinforcing fiber is concentrated in a main stress region under the surface of the rail bearing regions. The reinforcing fiber arranged in a region with a large stress is more than the reinforcing fiber arranged in a region with a small stress.

A monoblock concrete crosstie for railway tracks that achieves a high performance in operation includes a steel structure that is formed from ultra-resistant high strength steel plates embedded in a concrete element and having pre-stressed cold rolled wires with ends that form button head knots which are anchored to the steel plates. The crosstie includes rail seats with a convex channeled formation that is mateable with an extending member of a faceplate wherein the railseat has a width less than the width of the faceplate, and a center of the face plate has a first distance from a center of the concrete element and a center of the rails seat has a second distance from the center of the concrete element, the first distance greater than the second distance.
