Splice bar

This is the element on which the rails are supported and fastened and which they transversally bridge. The rails are joined to the splice bars by means of a fastening system; at the same time these rest on a layer of ballast to which they transmit the rail's loads. Spice bars can be wooden, metallic or cement. The cement ones can be of the bi-block style with two cement fingers under the track bridged by a steel bar, or of the one piece mono-block style. They can be substituted by pre-stressed or post-tensioned sheets of cement.
