MP #1862 GP18 torpedo boat

[mopac]

I want to modell MPs GP18 #1862.

For that loco I need a new longer tank as it is under the P2K model.

Any ideas, which tank can be used ?

Although it is not yet clear to the tank, I have already started Missouri Pacific # 1862 GP18 – a LL P2k model.

And GP7 # 146 will be changed to #1787 with eagle emblem.

Boy, Joerg, that GP7 really takes me back. One of those geeps passed my high school every day in the early 60s, out in the morning and back in the evening, with a “dodger” local although it dodged nothing really, it was the only train out on the branch. It ran down the middle of the street along the side of the school about 5 mph, with a flagman on the footboard. At each cross street the train would slow to a crawl for the flagman to walk out in front. The single tone EMD horn would bamp, the flagman would get back on after the intersection, and the train would get up to 5 mph again to the next intersection and then go down to a crawl again. The T&NO main line ran parallel a block away and in 1968 the MP worked out a trackage rights deal with them and ripped out the street running portion of the branch that passed our school. I’m glad I got to see that line, a picture of branchline railroading that does not exist any more.

Are there any measurements of the tank for the GP18s used by MoPac ?

It’s length will help a lot. I will try to draw a 3D CAD drawing to let it print at shapeways.

Because I still have a second GP18 made by LL P2K, which tank is also wrong. It should become #1962.

Hope I can do it. It will be my first 3d CAD drawing.

Forgive for asking what everyone else probably already knows. Whet are the “torpedo” tanks for? And why are they on top of the engine?

[mopac]

Anyone correct me if I am wrong but these are the air reservoir storage tanks which were moved from under the frame of the locomotive. They were located next to the fuel tank. By moving these to the top of the locomotive a larger capacity fuel tank could be installed.

First step of weathering : fading the blue

The “torpedo boat” has to wait for a new set of decals. I have placed it as a comparison.

Joerg contact me off list if you could.

Pat,

you’ve got a PM

Weathering of the MoPac Geeps goes on.

First try of MIG Panel line wash on the louvers and doors of #1787.

I still have to smooth it a little bit with White Spirit thinner

[peggyrothschild]

This is coming along nicely, who’s locomotive shell are you using? You mention using Mig pigments. What colors are you using. I’ve started weathering my Athearn Genesis GP15-1 but am going slow. It’s easy (for me at least) to over do the weathering

[mopac]

Charlie,

it is a P2K Geep. Painted with Badger Jenks’s blue.

I’m not using pigments. I used Vallejo white wash and MIG medium gray panel line wash.

Submission is a photo of #1787 in that scheme.

Joerg,

Scott Chatfield produced drawings of the typical EMD tanks on GP7, GP9, GP18, GP20 and I included them for reference. Looking at diagrams from 1976 – MP 1862 had a 2000 gallon tank and 1787 had a 1600 gallon tank.
