ESU set these six axle locomotives, which were often called the „German Crocodiles“ due to their articulated three-part frame, a memorial. The ESU model has a finely detailed metal housing and cowls. Numerous separately applied detail parts (either metal or plastic) perfectly render the powerful appearance of the prototype. Of course, we have taken into account the prototypical differences of the metal chassis according to the era. The different number of sand boxes, the realization of wooden and metal treads on the roof and, of course, the type of headlights are distinctive examples of the accuracy applied to these models. It goes without saying that the headlights are free-standing rather than simply projections from the housing. The delicate pantographs can be remotely controlled from your command station respectively your throttle and can be separately raised and lowered. During shunting only the lower right hand headlight is turned on at either end. This as well as the cabin interior lights can be switched separately. The model is also equipped with the sensors for situational sounds in curves or on turnout ladders, as well as a LokSound V4.0 M4 decoder with two speakers and a USP unit assuring reliable operation even on dirty tracks or extensive turnout arrangements. Due to the RailCom Plus® functionality the locomotive automatically registers with suitable command stations (e.g.: ESU ECoS). Of course, this model also has the universal electronics with plug-in current collector and universal wheel sets, which has already been proven on other ESU models. Naturally the LokSound decoder plays original sounds of an E94. In order to have sufficient space for the speaker and the enclosure each bogie has its own coreless motor complete with flywheel driving two axles. Four traction tires make sure the locomotive can transfer its power to the tracks. For perfect current pick-up the centre axles of each bogie are sprung.
