PERFECCIONAMIENTOS EN DISPOSITIVOS MOVILES SOBRE RUEDAS PARARECAMBIAR VIAS COMPUESTAS DE CARRILES Y TRAVIESAS O SOLAMEN-TE DICHAS TRAVIESAS EN SUCESION CONTINUA.

摘要

A track renewal train equipped for continuous replacement of track rails and ties has a first train section mounted for movement on an old track section, a second train section mounted for movement on a new track section, and an intermediate train section consisting of a carrier frame and linking the first and second train sections, the carrier frame bridging a trackless intermediate right of way section. The two ends of the carrier frame are coupled to undercarriages respectively running on the old and new track sections and the carrier frame consists of two parts. A vertical pivot couples the two carrier frame parts together for pivotal movement in a plane parallel to the track and a device is provided for pivoting the two carrier frame parts in this plane and for fixing the same in selected positions.
