In a method for renewing a track (2) and cleaning a ballast bed (3), the old track (2) is lifted off the ballast bed in sections as a track panel (15), transported forward in a working direction (4) and deposited on track panel wagons (8). The exposed ballast bed (3), forming a renewal gap (17), is cleaned by a cleaning machine (11), spoil (32) accruing in the process is transported forward underneath the track panels (15) deposited on the track panel wagons (8), and stored in hopper cars (10). New rails (29), pre-deposited underneath new sleepers (27) positioned on sleeper wagons (14), are pulled forward into the renewal gap (17) by the cleaning machine (11) and deposited on the cleaned ballast bed (3). The new sleepers (27) are laid down on the cleaned ballast bed and connected to the new rails (29) lifted off the ballast bed (3).

Systems and methods for using a mobile crane assembly are provided. The mobile crane assembly includes a mobile crane having a first truss assembly and a second truss assembly spaced apart and movable relative to one another. The first truss assembly and the second truss assembly are each coupled to a rail car end assembly. The mobile crane further comprises an upper gantry assembly movable along the first truss assembly and the second truss assembly. A flat cart is coupled to the rail car end assembly, and a material handling cart is received upon the flat cart and is configured to move between the flat cart and the rail car end assembly based upon input from a controller in electrical communication with the upper gantry assembly.

A clamp assembly may include a housing that can be positionable alongside an elongated body, one or more clamps that can be pivotally couplable with the housing, and an actuator that may pivot the one or more clamps relative to the housing. The clamps may selectively engage the elongated body to thereby restrict movement of the elongated body relative to the housing.
