      Travers Morgan Railways recognized this fact in 1990 and have developed a computerized technique to derive the true kinematic enveleope for indivdual rolling stock using basic vehicle parameters.

      However, in one respect Eurostar did condition the kinematic enveleope of Le Shuttle. […] The smaller Eurostar trains needed a lower step to overcome the height and width differential between the doorway and the walkway. This lower step became a significant element in determining the kinematic enveleope for the Shuttle trains, because of the limited clearance which resulted from its introduction into tunnel design.

      A publication known as “Design Guide BaSS 501” provided a methodology wherby the kinematic enveleope of a vehicle (the space required by a given vehicle, moving at speed) at a specific location could be manually calculated from a number of input parameters.
