I have been creating O-gauge White Pass rolling stock for years. I found a computer model of a GE Shovelnose created by a talented 3D modeler named James Will. A few years ago James had a stroke and can only communicate with eye movement now. I spoke with James' Wife, who talked to James about it. He has given me permission to sell his model through the Shapeways platform. I also have done some modeling of rolling stock myself.
I scaled these White Pass models so that they are printable in O, S, HO, and N-scale. Available on Shapeways.com
These GE shovelnose locomotives are being sold off, by the White Pass and Yukon Route Railroad, and may soon appear at a narrow gauge railroad near you. The containers were used for hauling ore from the Anvil mine in the 70s and 80s.
