Model railway enthusiasts who put together prototypical trains and design and build contemporary scenes with meticulous attention to detail also want to run their trains at speeds appropriate to the originals. Accordingly, the chronograph's tachymeter is calibrated to a model railway scale. Thus the speed of a fast model ICE can be measured just as accurately as that of a historic steam locomotive.
