Here's a little teaser from the upcoming large construction set. The Crocodile Ce 6/8 is one of the first regularly operated electric locomotives and also one of the most popular models for railway enthusiasts. The inspiration for this set was its oldest variant used on the Gotthard railway. The model is in "I" scale 1:32 with a track gauge of 45mm, consisting of over eight hundred metal parts and several thousand pieces of fasteners. The total length over the buffers is 625mm (25").

  The aim was to build it without special parts. When constructing such a complex model, you often find yourself stuck, tempted to create a custom piece to solve the problem easily. This approach is common, easy, and a bit cowardly. Notice how all construction set manufacturers keep expanding their catalogues with new parts, and I'm not just talking about metal sets; it's the same with plastics. A notable exception is TRIX, whose designers have managed to stick with the same parts throughout production.
  So, how did my resolution fare? Like most resolutions, it resulted in two new parts: a turned buffer body and a metal handle.

  And here's the final result. I somewhat underestimated the amount of work involved.
  The construction mirrors the original, with two articulated bogies as the base. Above them is the superstructure, housing the transformers and driver cabins. As it goes through curves, the bogies under the cabin can move freely and follow the track's radius.
  The model isn't powered, but it is mobile. The wheels turn, and the connecting rods are movable, with the motor rods timed at 90° to avoid getting stuck at dead points. The pantographs can also be raised.
  The tracks the model is posing on are standard "I" size from manufacturer PECO.
