DIN EN 13129:2013-12

This European Standard applies to main line rail vehicles carrying passengers. It does not apply to suburban vehicles, metros, tramways and driver's cabs. This European Standard establishes comfort parameters for compartments or saloons (single level or double-decker). These comfort parameters apply in a similar way to the areas reserved for train staff. The standard also specifies the conditions and the comfort parameter measurement methods for compartments or saloons.
