I have a bit of a dumb question. I recall reading in a N Scale magazine a few years ago about a conversion someone did of an atlas GP 7 TT from a high hood to a low hood, and did it up in proper MoPac fashion. I can't find my issue of the magazine to see if the answer i seek is in it or not. Did MoPac have any torpedo tube equipped GP7s? If so, were they high hood, or low hood? Any road numbers would be a big help. Thanks in advance.
MoPac did have GP-7 TT's I have an atlas N scale and have seen pictures on the web in the past. I think maybe on the Missouri Pacific Historical Society website.
MoPac, Thanks, i did some looking at their website, but if it's there, i missed it. but the wife says i am blind more often than not, so i'll check again. i appreciate the response!
check both of these links This one looks like it had the nose chopped but is a TT. Unfortunately they don't have an actual label on it telling what model it is. http://www.mopac.org/photos_diesel/mp300l.jpg If you zoom in on this one you can see the TT...they only list it as a GP. http://www.mopac.org/photos_diesel/mp325.jpg
This may take a minute. Did some digging through the book Missouri Pacific Diesel Power and came up with the following GP-7 info: Steam generator equipped 4241-4248, later 309-315. Rebuilt by MP to GP-7u with chop nose, 2500 gal fuel tank, removal of footboard and installation of snow plow. 4247/314 was not chop nosed. 4256-4260, later 322-326. Also became GP-7u 4316-4322, later 327-333. Became GP-7u Based on my reading, all these units came as TT's, but the rework by MP (into the "u" corresponds with the change into the 300 number series.
so... if i get a plow added and remove the footboard, i shouldn't have to try and chop the nose? i can't remember what size fuel tank they came with.... ?????
If you were to stay with the high hood, only 314 would be correct. If you just like the TT without the modifications (high hood, no plow) just use the original number series. As far as the fuel tank, I'd believe that any of the TT's should reasonably stand in, but that's a matter of preference, since it's my understanding that the air tanks were moved to the roof to leave room for water storage for the steam generator. I believe that the water tank was in conjunction with the fuel tank, so it should look OK, but I definately won't claim to be the last word on that.
Usually the partition in the original fuel tank was removed (N&W had some former TT units converted to freight service as well) To do a low-nose conersion is pretty simple and quick, get an Atlas low-nose SD24 shell and cab, cut the nose off the shell, cut the high-nose off the T shell and bam... you're done. Most likely have to cut the mechansism down though (though i believe the newer Life-like GP18 mech can be used)
ok, i get ya now. Thanks to everyone for the information and input, now just to go and find some pictures . I may leave it as 314 b/c i have a brand new undec TT unit that runs great. of course, cutting the mechanism down shouldn't be too hard. so i'll have to think about it. i tried calling atlas yesterday to order some replacement handrails and airhorns for one of my SD60s that had an accident, but they are doing inventory for the next couple of weeks, so i have some time to think about it. i'll make sure and post some pics to my railimages when i get it finished in a couple of months. thanks again!
Here and here are some pictures of modified GP7's. Here and here are some shots of the as delivered units. And the disclaimer - these photos are copyright to the site owner, but it's a wonderful reference site.
eagle2, Thanks a bunch dude. i completely forgot about that website. those are some great profile shots for what i am needing. thanks! beast5420
