On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward configuration. The former arrangement is now the norm in North America for all types of diesel or electric locomotives, in Europe, most modern locomotives are cab units with two cabs, one at each end. However, the locomotives powering some high speed European trains are normally cab units with one cab, on self-propelled rail vehicles, the cab may be at one or both ends. In addition to the controls, a cab will typically be fitted with windshields, rectangular side windows, crew seats, heating. By about 1850, high speed Crampton locomotives operating in Europe already had a much needed windshield giving some protection to the footplate area, some other early locomotives were even fitted with a cab as part of a rebuilding program, an example being the locomotive John Bull. In Germany, the cab was introduced by the Saxon railway director. However, until 1950 the railway directorates of the German-speaking countries continued to believe that a standing posture was essential to maximise crew vigilance and this unsatisfactory situation changed—with few exceptions—only with the construction of the German standard electric locomotives, which for the first time were equipped with crew seats. Meanwhile, the maintenance of crew vigilance became possible by technical means through the use of Sifa devices, cockpit Control car Control stand Driving Van Trailer Push–pull train This article is based upon a translation of the German-language version as at April 2010
