Files for a GP11 EMD locomotive in HO (1:87) and N (1:160) scales. Included are printable STL files as well as Sketchup files for the locomotive in HO and N. The Sketchup files are water tight, print ready, and can be edited and rescaled. Note that the scaling in the Sketchup files is ten times larger than the scale size due to Sketchup performing poorly at tiny scales. The HO model is designed for Plano GP7/9 Intake Screen #14860, GP7/9 Intake Shutters Set #14861, Cannon and Co 1707 36 In Cap Top Radiator Fan, and EMD stanchions. Will fit most gp7/9 frames with minor modification required, especially old P2K frames. The N scale model fits a slightly modified Atlas GP7/9 frame (easily done with a dremel) to fit the low nose. Also included are some files for making a dummy locomotive, which includes printable Blomberg trucks, a tank, and chassis. (Note: In tandem with Kaslo Shops turn this models as been turned into a resin kit in HO scale. https://3dcentraltrains.com/collections/locomotives/products/hl-42-paducah-shops-rebuilt-gp-11-36-fan-locomotive-shell-kit https://3dcentraltrains.com/collections/locomotives/products/hl-43-paducah-shops-rebuilt-gp-11-48-fan-locomotive-shell-kit.)
