Today I bring sort of a "sequel" model to my previous GWR 5700, in that they're both built in the same general style and to scale with the drivers. This does mean that they are not perfectly to scale with each other, however it was a scale I felt I could best capture the nuances of their shapes.
One last thing I want to address before I post a picture is the colour: The engine is red. Ideally it would have been green, or black. However green wasn't possible for me due to both costs and part rarity; and I ended up not wanting black due to the fact that, well, you can only have so many black engines before you get colour-bored!

This engine is basically 90% SNOT above the running board.




The most difficult part of the model for me was the integration of the boiler into the water tanks on the sides. I had a lot of very strict rules for myself, proportions had to be as close as I could get, and I did not want any unsightly gaps. Eventually I ended up being able to get these slopes to line up just right, and the fact that I had previously been insistent on a step on the front of the water tank helped hide the gap there.
The original build actually was motorized by a pair of adjacent M-Motors hidden under the boiler and between the water tanks. While the strength of the system worked marvelously, it led to some structural and drive issues thanks to the trailing wheels articulation. The structural issues were overcome, however the center of gravity is between the 2nd and 3rd axle meaning that curves with even slight gradients sent the front wheels off the track. I ran a lot of experimentation with different builds and rubber bands, but it seemed to be an inescapable problem thanks to wheels and body shape. The current version is therefor unpowered, however it does roll very smoothly and a powered coach solves the motorization problem.
I hope you all enjoyed my engine! I should hopefully be posting a few more within the near future!
