<p>A composite continuous surface rail is constructed by combining a load-bearing support rail (10) divided into segments to allow for thermal expansion with a continuous surface rail (16) that slideably engages the support rail and spans any number of support rail segments. The continuous top or surface rail (16) includes a running rail (16) and an expansion rail (28). The expansion rail (28) is provided to absorb thermal expansion of the running rail (16) while continuing to provide a continuous composite rail surface. The surface rail (16) and/or support rail (10) may be electrified. An electrified running rail and expansion rail will provide an electrified composite rail with electrical continuity.</p> |
