For anyone interested, a new “vignette” (article) is now published on Greg E’s Web site with respect to the USA Trains GP7/9 diesel loco.
Items covered include the following:
3-D Printed Components & Installation
( I used this technology to mount Kadee centerset couplers in a 3-D printed coupler box and other parts on the GP7/9 from the start rather than using discretely made parts)
Non Coupler (other Issues) include:
Dismantling Loco
Intermittent Switches
Cab Removal
Adding Extra Weight
Cooling Fan Experiment
“B” Unit Adaptation
Shown below is an example USAT SP loco with installed factory and the 3-D printed components.
The “B” Unit:
Prototype railroads Santa Fe, Pennsylvania & Union Pacific had “Geep” B units.
Shown below is a “B” unit conversion on a USAT UP loco with pre-production 3-D printed parts.
For full detailed info., see vignette, title:
“USA Trains GP7/9 … with 3-D Printed Components (and other issues)”
If desiring to obtain 3-D printed components or interested in the Geep B unit conversion, contact Colin Camarillo via his Web site.
