ORHS 471 - GP7u Locomotive for Dragon Railway
Print Profile(1)

Description
This is rambros' excellent EMD GP7 model for Dragon Railway, remixed into a GP7u and with an ORHS 471 livery.
ORHS 471 is an EMD GP7u owned by the Orrville Railroad Heritage Society of Orrville, Ohio. It started life in 1950 as MEC 571, a standard GP7. After 35 years of service it was upgraded by Maine Central's Waterville shop to have a unique crew cab and dynamic brakes, and was renumbered #471. Following a period of service with the Connecticut Department of Transportation it was retired and acquired by the ORHS to pull excursion trains.
As far as I know, #471 is the only GP7u with this style of crew cab. See the ORHS site for more: https://orrvillerailroad.com/equipment.html
This contains the new files for the ORHS livery, the rest of the parts and assembly manual can be found on the original model page: https://makerworld.com/en/models/410861
I've included the pre-bent models for the railings. I found these easier to install and better looking than trying to hand bend the flat railings. The 3MF shows how I oriented and supported these.
The K5LA horn included is by manimal and can be found here: https://www.thingiverse.com/thing:4088789
Under Files there are individual STLs for all the new and remixed files. For the body and lid there are one piece STLs that can be printed single color (no livery), and split STLs in a seperate folder for multi-color printing. There is also a Bambu 3mf with the entire locomotive colored oriented and supported.
The small details (horn, bell, bell mount, MU stands, and number plates) had to be printed with a .2 mm nozzle, the rest can be printed with a .4 nozzle.
I used PLA for everything except the drive gear, which should be PETG or ABS. I've had the little gear on the motor strip out when printed in PLA.
