    Prototype: At the end of the 1960-ies the DB realised that the necessary acceleration of freight traffic will not be possible with the then available electric locomotive designs. The four axle class 140 was not powerful enough at higher speed and the more powerful class 150 with a maximum speed of 150 km/h was too slow. The most modern technology available to the DB was built into the multi system locomotives class 181 / 184 and, of course, into the express train star, the 103. Based on the proven designs of the standard layout electric locomotive family the company Krupp designed a very elegant six axle engine that was more powerful than any faster locomotive and faster than any stronger German electric locomotive. Pantographs of the type DBS 54 were installed on the roof. With the finely detailed bogies derived from the class 103 and the harmoniously proportioned body with its large engine compartment windows the class 151 still is a good example of a stylish locomotive – even today. In 1972 the very first of the 170 locomotives class 151 was delivered to the DB. This first unit shows a few minor variations to the series production. Pronounced teething troubles, often encountered with new designs, were never an issue with class 151. Despite the fact that they were designed as freight service locomotives all engines of this series were equipped with push-pull remote control. The engines stationed at the depots in Nuremberg and Hagen-Eckesey were hauling 3,000 ton freight trains just as well as local services consisting of four refurbished wagons. On the Frankenwald line they pulled the inter-zone passenger trains for a period of four years. The impressive acceleration characteristics made her the first choice of motive power hauling express trains and later also Interregio Trains on main lines with steep gradients. Therefore this kind service can be found in the duty roster right through to the late 1990-ies. Since 1976 some of these six axle locomotives were equipped with automatic couplers and double headed heavy ore trains consisting of up to 28 six axle hoppers weighing in at 5,400 tons, for instance from Duisburg to the steel works Dillinger Hütte in Saarland. Class 151 locomotives came regularly to Vienna, Austria. No other DB locomotive could be so freely assigned to virtually any kind of duty. For this reason these six axle locomotives were deployed across the entire area of Germany until 1990 and after reunification also in the new provinces of the country. Today the situation of the class 151 is not what it used to be. Four axle locomotives of class 145, 152, 182 (Taurus) and 185 equipped with three-phase A.C. drive technology put less strain on the tracks compared to the six axle design. They also have a higher maximum speed and – at least under normal weather conditions – are equal to class 151 in terms of draw-bar pull. The younger class 155 from the DR (ex DR class 250) competes with the 151s since 1990. Although only locomotives with some damage were decommissioned until 2009 this changed in 2010 when many engines whose operating term had expired were put out of service. But do not fear, dear friends of the 151; there are locomotives who received a major overhaul in 2010. According to the rules the engine may be in service for another eight years

    Model: We have equipped these class 151 locomotives with all contemporary functions so you can deploy them for any service on your layout. The powerful five-pole ESU motor provides its power via a combination of worm gear / helical gear box to four axles. The centre axle of each bogie is sprung loaded and helps with current pick-up. Due to the large weight of 600 grams and four traction tires the locomotive virtually claws itself onto the tracks and – if needed - drags a 28 car ore train around your H0 layout on its own where the prototype needs a double header. Of course, there is a LokSound V4.0 decoder on board generating powerful sound and controlling the manifold lighting options. The clank of the wheels on turnouts or their squeal in tight curves can also be heard at slow speed. As it is the case with the prototype the cooling of the traction motors and the oil radiator are switched on automatically when needed. For optimal reproduction of high and lower frequencies the 151 has a new 28mm circular speaker with an impedance of 4 Ohms. As you would expect from an ESU decoder it understands both Motorola and DCC commands. Since the decoder is already RailComPlus implemented it will register automatically with command stations supporting RailComPlus.
    By mounting or removing the supplied current pick-up you decide whether the model is suitable for 2-rail or 3-rail systems. Simply clip the centre pick-up on or take it off – that's it! This happens within seconds without any tools or soldering and without taking off the body. The model runs well on all popular 2-rail track systems as well as on Märklin® C track or K track. For a strong link between the loco and the train there is a coupler shaft as per NEM 362 held in short coupling kinematic.
    That the chassis is made of metal probably does not surprise anybody. However, the body and the gear boxes are also made of metal.  Of course the body bears all appropriate details and the correct number plates. The roof equipment is quite impressive and invites you to spend more than a glance on the details. Different insulators, a main switch assembled of various parts and separately applied steps are just some of the features. The pantographs are fastened to the body with the four insulators.
    The pantographs that can be raised and lowered by remote control are a particular highlight: Newly developed servos move the pantographs like with the prototype and without any disturbing rods. Of course, the movement is supported by the appropriate sounds. The simulation of the sparks caused by the brakes with several LEDs is a world´s first. The sparks only appear during a rapid slow down. Thus the heavy work of the locomotive also becomes visual - a nice play in miniature and not only at night.

    Model & Prototype Information

    The German Class 151 heavy electric freight locomotives were built for German Federal Railway between 1972 and 1978. They were built as a replacement for the ageing Class 150's, 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.  On the 21st of November 1972 the first locomotive, 151001, was delivered by AEG and Krupp. It was followed by 11 further pilot locomotives, which were extensively tested before the main order was built. Altogether 170 locomotives were ordered, which were based at first in Hagen and Nuremberg. Originally the Class 151 was also suitable for passenger service, however at present it is not possible because they are not fitted with safety equipment. Some engines were fitted with automatic coupling (type unicupler A69e) to haul heavy ore-trains.
