HI gang,
AT&SF GP50 anti climbers which variant is used, sharp or rounded corner? I can't tell one way or another looking at the proto t pictures I've reviewed. If I had to decide based on what I've seen so far, they are the rounded corner type seen on later model SD50s.
Would that be correct?
Thanks

No, they didn't. The rear had the pointed anticlimbers like on the early Athearn BB models. They have rounded corners also but have a much more pointed center deck. I believe it's a Cannon 2105. The front anticlimbers were more like the Cannon 2103.
Cheers, Mike

Basically the same as the GP40X then it would appear.

Yes, The GP40X was the precursor to the Phase I GP50 and they shared some features. The Phase II GP50 has anticlimbers like the Cannon AC-2103 front and rear. They have the rounded corners and the overhanging deckplate like on the Athearn GP-60 shell. The 30 ATSF Phase I units were numbered 3810 to 3839. The 15 ATSF Phase II units were numbered 3840 to 3854. The anticlimbers and the blower housings are the major external differences between the two. A very easy model of a Phase II could be made with an Athearn GP-60 shell and GP-50 dynamic hatch. There is an overall length difference of about six inches on the prototypes. The Athearn models share the same bodies and chassis. They had minor differences in the rooftop appliance locations. Study your pictures and timeframes. I hope this helps...  Mike |

[''.....''] I hope this helps... Mike Belated thanks Mike, it certainly did. One final question on this topic (probably just made a liar of myself  ).. What about the stanchions on the rear of these AT&SF phase I '50's (again, can't find detailed rear photos anywhere), were all four stanchions mounted vertically through the flat outer edge of the anticlimber or did the two outside stanchions mount on the outside rim of anti-c? i.e. like the stanchion arrangement on D&RGW SD 50's if you're familiar with those. Thanks!

Hi Robert,
Yes, I'm familiar with the SD-50 setup. That wouldn't be right for this one. I looked through a bunch of my stuff. Most photos were inconclusive. I looked at an old Dave Hussey GP-50 build article in Model Railroading(Jan-Feb 1995) in it he stated you need to fill all four holes with plastic rod as all four are mounted on top for the PhI.
Cheers, Mike

Hi Robert, in it he stated you need to fill all four holes with plastic rod as all four are mounted on top for the PhI. Cheers, Mike Well that sure is a break for me b/c I'm having a fit attempting to securely mount those outside mounted ''forked'' type smokey valley stanchions on my early phase SD50 models... guess I'll just have to let 'em secure themselves solely from the solder joint at the hand rail. Thanks for the info Chief, very helpful as I attempt to model in absolute prototypical fidelity. |
