Upgraded file. Body shell only. Requires A Series Floor to complete. www.shapeways.com/product/SE6QMMH4V/n-scale-rocky-mountaineer-a-series-floor-updated. Wheel trucks not included. I use Micro Trains #1017 Commonwealth 4-wheel Passenger Trucks. I use MicroScale #1023 Body Mounted couplers. The story behind my developing these models. First off, on a trip to Canada I had the pleasure of travelling on the Rocky Mountaineer train and I just had to have a model of my own. No manufacture had made models of the Rocky Mountaineer Ultradome cars so I had to work out some other means of getting the train. I tried several scratch building methods, but they all fell short somewhere, usually with the curved dome windows. The best result I achieved was by drawing the cars on the computer, then laminating the print and moulding it over a form to get the shape, and attaching the body to a scratch-built chassis. Though a fairly satisfactory result, I thought I could do better. Eventually I learnt about 3D printing and thought this could be the answer. After a long period of learning the design process I came up with all the variations required. I chose to leave the upper dome windows solid as on the Rocky Mountaineer cars they have several layers of window tint applied to shield the passengers from the sun and Ultra-violet rays. The lower windows only have a couple of layers of window tint, so I cut these out so you can see the interiors (if you want to add these features to your model) I have cast windows for the lower level windows – both clear and solid – that just press into place. These are available from me on request.
