The GP-9 is a fantastic locomotive to detail and weather. It is unique because all GP-7's, GP-9's GP-18's and GP-20's in N scale have interchangeable parts. This allows you to kit bash many variations of these locomotives when it comes time to kit bash them and detail them. Most modelers don't know that all the parts of the GP-7, GP-9, GP-18 and GP-20 in N scale are interchangeable. I'll be using Sunrise Enterprises detail parts for the GP locomotive. Sunrise Enterprises is no longer in business, but I was able to accumulate many of their different detail parts to use on many SP, ATSF and Southern diesel locomotives on the roster of the "New" JJJ&E. Few manufacturers today specialize in supplying the N scale modeler with quality detail parts.
It was fun to work on the SP GP-9. I detailed two of these locomotives, SP #3509 and SP #3498. I used a Dremel tool with very fine diamond points to drill the holes for the detail parts on the locomotive shell and frame.

These parts include MU hoses, MU Cables Round MU Stands, Antennae, Steam Generators, Rotary Beacons & Stands, High Stacks, Over head Air Tanks, Spare Knuckle Coupler and Speed Recorders. All of these detail parts were used on SP #3509 GP-9 and SP #3498 GP-9. |

All the detailing of this SP #3509 GP-9 took about 90 minutes to complete. The next step is to weather this diesel with the Bragdon Weathering System. I already added the detail parts to SP #3498 and weathered the locomotive with the Bragdon Weathering System. I'll post these photo's in a few days.
The photo's below are the initial weathering of SP #3498 Phase 1 GP-9 with the Bragdon Weathering System. The weathering can be toned down by brushing the excess weathering powders from the diesel shell.
