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.

A band adapted for use as a seal around an upper edge of a boot adapted for holding a block to which a rail is fastened, includes an elongated body having an outer face, an inner face, a first end and a second end. The first and second ends of the elongated body are secured to each other to form the band. An inner face of the elongated body is smooth and an outer face thereof includes a plurality of laterally spaced ribs. The ribs extend from the first end of the band to the second end thereof. The elongated body is made from an electrically insulating elastomeric material.
