Device and method for building a new ballastway for a rail line

A method for building a new ballastway for an at least single-track rail line (100, 101) for an initially non-existing track, wherein the new ballastway comprises at least a PS layer (2) and a ballast layer (3) and the PS layer (2) is built on a ground subgrade (1) and the ballast layer (3) is built on the PS layer (2) in a continuous work sequence in a working direction (A), the method comprising:

• building the PS layer (2) by a PS layer finisher (20) (PSL finisher) and building the ballast layer (3) by a ballast bed finisher (30), the ballast bed finisher (30) operated at a predetermined distance behind the PSL finisher (20) in relation to the working direction (A) and provided with a chain or crawler running gear (31) for traveling on the PS layer (2),
• supplying material (K) required for building the PS layer (2) to the PSL finisher (20) by a respective correlated conveying device (12a) from at least one open-top car (10a, 10b) and supplying material (S) required for building the ballast layer (3) to the ballast bed finisher (30) by a respective correlated conveying device (12b) from the at least one open-top car (10a, 10b), the at least one open-top car (10a, 10b) operated at a predetermined distance in front of the PSL finisher (20) in relation to the working direction (A).
