SP Narrow-Gauge Locomotive #18 - Nn3 - Digital File

Originally built by Baldwin in 1911 for the N-C-O and acquired by the Southern Pacific in 1928 for use on the ex-Carson & Colorado right-of-way through the Nevada and California desert from Mound House near Carson City, Nevada, to Keeler, California, in the Mojave Desert (the famous “Slim Princess” railroad). It has been restored by the Carson & Colorado Railway volunteer group. ( https://carsoncolorado.com/ )

This file is for the superstructure only (boiler and cab) to be downloaded by the modeler and then sent to a vendor who provides lost-wax casting services using the customers digital files (such as Shapeways and Sculpteo.) The rrsulting casting is to be used with the resin parts available separately at: Southern Pacific Narrow Gauge Locomotive #18 - Nn3 – 3Dp Train on this site to convert one Rokuhan Z-scale 4-6-2 (C-57) model to Nn3. The builder will need to provide the C-57, a longer screw for the tender frame extension and screws for attaching the tender shell to the tender frame, a Micro Trains Line 905 Nn3 coupler, Gold Medal Models etched handrail stanchions, brass wire for railings, paint and decals and optional LED lamps, resistors, and 36AWG wire for electrically connecting locomotive frame to tender-mounted motor. (See Instructions with resin kit - link below.) The brass casting will need to be insulated from the Rokuhan die-cast chassis (suggest using cigarette paper).

READ BEFORE DOWNLOADING:

I do not guarantee you will be able to get castings from either service, but the files I provide for download will be ones I have previously had successfully cast by Sculpteo. Since these files are “pushing the limits” on details such as free standing piping and rivets, you will probably need to use a “print it anyway” option. I also do not guarantee all details will successfully reproduce every time the part is cast, but they have on castings I have previously ordered from Sculpteo, as shown in the photo.
