English to French Tech/Engineering Transport / Transportation / Shipping Guide for the application of STI

Consistency of the snow as everything from very loose and light to ice- or concrete-like, from dry to near soak-wet snow with any density from 100-400 kg/m3:
Heavy snow causes high resistance when running into it.
Appropriate strength of primarily the snow plough and its fastenings and the front of the rolling stock is necessary (see point on obstacle deflector in the TSI).
In addition **openly mounted under-floor equipment** needs enforced protection to avoid harm from e.g. ice lumps.
