摘要

Method for exchanging two-block sleepers (2) of a track (3) formed by concrete blocks (5) connected together by a steel support (4) comprises separating the steel support from the concrete blocks and positioning in a container (24), moving rail running gears (8) on rails (7) connected to the concrete blocks, lifting the rails from the concrete blocks between two rail running gears and storing in containers (33) and placing new sleepers (36) on a ballast (6). An independent claim is also included for a machine for exchanging two-block sleepers of a track formed by concrete blocks connected together by a steel support. Preferred Features: The containers containing the new sleepers are filled with the concrete blocks.
