TRAXX AC3 BLS
Although it doesn't look that different from my previous iteration, almost every part the model is at least somewhat different.
Last March I posted a render of a new drive system that I had hoped to use in this model; however, after finally building it in real life and testing it with an actual consist, I found that it had a sizable drawback that made it impractical. Namely, the technic turnable did not allow for the bogie to pitch even slightly. This resulted in a few derailments when negotiating inclines of even a plate per 16 studs.
When I decided to scrap this drive system, I kept the technic beams to serve as a central beam from which I could build off of. This also meant that I could orient the buwizz downwards so that the roof would not need to be removed for access.
I spent quite a lot of time on the roof to incorporate correctly sized and placed vents as well as the wiring. The side vents just below the pantographs were very difficult to place as since the 2x4 dark azure tiles (I would have liked to use 2x3 tiles - similar to my previous model) blocked any access to the main technic frame. As a result these vent tiles are connected to 3mm tubing with droid arms which are simply forced into place by the roof. The DBG roof tiles are held together by a 2x8 plate down the center with 2x2 turntable tops on either side. I was very pleased that I was able to make the rear part of the cab roof flush with the main roof and then jump up one plate near near the front.
I have to thank the various builders who worked on the DB Traxx 2 from which I used to improve the lower area below each cab as well as the slanted cab roof.
