DB BR Class 151 The Class 151 is an electric heavy freight locomotive built for German Federal Railways between 1972 and 1978. They were built as a replacement for the ageing Class 150, in order to cope with the increased requirements of this type of locomotive, in particular the desire of a 120 km/h (75 mph) top speed. DB BR Cargo Class 140 The class E 40 basically is a class E 10 without electric brake, altered gear ratio for lower speed and correspondingly higher tractive effort along with additional minor changes. As all other types of the Einheitslokomotiven program the class E 40 had welded bogies with central pins. Instead the formerly used axle hung motors it used a quill drive with a circular rubber spring as a connecting element ("Gummiringfeder" in German) reducing unsprung mass. The control unit had 28 power settings.879 units were built, making it the Einheitslokomotive (standard locomotive) of its era. The original speed was 100 km/h, this was enhanced to 110 km/h in 1969 in order to allow better usability also for commuter trains. A sub-series, known as 140.8, were equipped for push-pull train operation. In 1968 class E 40 was renumbered to class 140. DB BR Cargo Class 294 From 1995, large numbers of locomotives of the class were fitted a different type of radio remote produced by Krauss-Maffei (KM)The remote device is carried by remote train driver (German:Lokrangierführer LRF ) in a so-called "Belly Box" (see Remote control locomotive for details) and operated in a manner similar to that of a toy car or model aircraft remote control.This type of control is used in shunting operations and was previously used with smaller shunting locomotives such as the DB Class V 60 and DB Class Köf III (DB class 331 to 335)The rebuilt locomotives of the 290 series form Class 294, rebuilt locomotives of the 291 series form Class 295The locomotives have radio receiver in the cab, the LRF (remote train driver) must manually turn on the locomotive cab radio using a key switch on the locomotives control panel. A vehicle equipped with this type of remote control has a lamp above the cab window that lights to indicate that the locomotive is capable of receiving the radio signal. This means that the remote train driver (LRF) can now operate the locomotive at the trackside.Various functions can be activated remotely - brakes, start, Vkonstant: i.e. running speed is automatically maintained, Sand, clutch etc. Currently only Abbelio FLIRT's “fly” on the Line,but these locomotives are historic!
