Bricks-on-Rails posted a topic in LEGO Train TechDear Community, The week has passed very fast once again and like promised I would like to present a model for the start of the weekend. But first a little text. Some of you may have already seen it while browsing through my Flickr channel. It's the "German Crocodile", the DR E 94. It was built from 1940 and was mainly used in heavy goods traffic in Germany and Austria. 200 units were built. The nickname "German crocodile" was given to the locomotive because of the optical similarity to the "Swiss crocodile, the SBB Ce 6/8", which comes much closer to a crocodile. But the real nickname is not "crocodile" but "iron pig". They were designed for freight trains with up to 2000 tons. This heavy electric locomotive fascinated me already as a child on our domestic model railway layout. Apparently effortlessly she pulled the at that time seemingly endless coal train over our 4m² plate. The model is approx. 43cm long, 8.5cm wide and approx. 12.5cm high, with extended pantographs even higher. The locomotive can be motorized with two Power-Functions M motors, one of which is housed in each "crocodile snout". The IR receiver and battery box fit easily into the spacious cab. Inside, it was even possible to design both cabs. The detailed roof can be removed for easy access to the interior details and electronics. The two chassis, each with three axles (all driven) are pivoted and also very detailed. Here were not the "standard railway wheels" used, but the large spoke wheels of the Emerald Night, as these fit much better to the scale. By the way, the size of the model fits perfectly to the already introduced "SBB De 4/4". What has always bothered me with this locomotive, as well as with the "sister" from Switzerland and other locomotives of similar design, is the relatively large gap, which is between the driver's cab and the two " mouths " (also to be seen with the crocodile from LEGO set 10183). This gap is usually quite large with LEGO models, as the available curve radius is very small compared to the scale. In the real model, however, the gap is hardly noticeable. My goal was to "develop" a system that allows cornering but keeps the gap as small as possible. The solution is relatively simple. Below the cab there is a kind of rail system which is attached to both " mouths " and thus enables the three elements to be pulled apart if necessary, e.g. in curves. On a straight line, the elements are pulled together again by means of an attached rubber band. The assembly attempts have left a good impression on me. Unfortunately also a long, heavy train causes, that the elements can pull each other a little bit apart when driving straight out. As with the "SBB De 4/4" it is possible to build the locomotive in three different colours: - dark green (still my favourite) - grey - blue (DB colouring) And now have fun looking at the pictures. Criticism welcome. The example (Source: Wikipedia) More pictures in the flickr album With kind regards Martin | Bricks-on-Rails
