Abstract
An apparatus for reconstructing railway track systems while simultaneously clearing away the bed of the old track system. A sliding seal driver is used to secure the trench formed by the removal of the old track foundation as the old track is cleared away. A new trench is cut as the apparatus proceeds on the same path as the old track. The seal driver includes lateral shields securing the trench walls as well as ground shields resting on the bottom of the trench. The lateral shields are of such lengths to secure the trench walls over the entire work area.
