A work train lays a rail of a railway track. The work train has a heating device with a heating zone, gas burners, and a radiant body interposed between the gas burners and the heating zone. The radiant body has openings that open into the heating zone. The work train is moved in a laying direction, so that at each moment a portion of the rail to be fixed passes through the heating zone. Heat is supplied to the rail to be fixed through the heating zone by feeding the gas burner so that no flame emerges from the openings in the heating zone and that at least 75% of the heat supplied to the rail is transmitted by radiation from the radiant body. Then the rail is fixed after the heat has been applied to a tie of the railway track behind the heating zone in the laying direction.

A floor conveyor belt (9), running in the car longitudinal direction and arranged in a storage container (8) and a transfer conveyor belt (11), arranged at an angle extending over a front end of the car chassis are provided on the above. At a rear end (12) of the floor conveyor belt (9) with relation to a transport direction (10), the storage car (1) has an excavator device (13) for picking up and removing the bulk material (27) on the floor conveyor belt (9). The excavator device (13) is arranged outside the storage container (8) and comprises an adjustable grab (31) operated by actuators (14, 15). The excavator device (13) further comprises a take-up conveyor belt (22) with a low take-up end (23) and an ejection end (24) positioned above the floor conveyor belt (9).
A bulk material loading wagon (1) with a storage box (8) has a floor conveyor belt (9) which runs in the longitudinal direction of the wagon and has a receiving end (10) and a discharge end (11). The latter is assigned a transfer conveyor belt (13) which is arranged at an angle to a plane (14) of the floor conveyor belt and protrudes over the storage box (8). A ballast sifting system (16) with a sifter (17) and a vibration drive (18) is arranged on an upper end region (15) of the storage box (8), which end region lies opposite the floor conveyor belt (9).
