Additional documentation in verification of requirements was requested only for the sleeper shoulders of the System rail-fastening system, which were slightly higher than for the W14 track.

Due to its shorter slabs and its bituminous sub-base, the system can adapt to ground settling without suffering irreversible damage to the prefabricated components. Bridge engineers are frequently responsible, for example, for approval of the concrete track supporting layer — and railway engineers, for approval of the track components.

Ultimately, the project dealt with two offices; one for the ballastlees components, and another for bridge construction for approval of the concrete components e.
