Superstructure tongue device for railway lines

摘要

The device has a rigid rail (2), a tongue rail (3) with support bed (5), and a separate wing rail (4). Rigid rail and support bed are one modular part, and form a long basic block (6). The wing rail is esp. screwed and/or welded to the block. The flat outer sides (24,26) of block and wing rail, and the underside (25) of the block, have a sound-insulating and/or electrically insulating jacketing. The basic block contains a heater chamber (28), which is sealed to the outside by the wing rail.
