The productivity of this aligning, tamping and levelling machine, of ongoing operation, is 50% higher than that of cyclic working machines. Its regular use has proved to extend railway track conservation intervals, with the consequent economic saving.

It has two tamping sets and a total of 48 tamping rods, which allows tamping three sleepers in one single work cycle, with outputs of 2,200 m/h, which makes it the most performing tamping machine in Spain.

It can face any aligning-tamping work both on Iberian and international gauge tracks.

Within its electronic equipment, it is necessary to emphasize the following systems:

· Operating system with and absolute reference and a fixed point.

· Computer-aided guidance system, with prior auscultation and computing geometry optimisation.

· 8-channel strip chart recorder of parameters of a railway track.
