N&W SD50 "S"

[Randy Earle]

Here is the full size drawing in 1/55 scale redrawn by myself in undecorated. The SD50-S model is the 1rst version of the SD50 built on a SD45-2 frame, so it shorter than the later SD50 and SD60 models. The same length as an SD40-2.

I was wrong about the first SD40-2, but I'm right about this SD50 S. I have some of the parts to build this one now. I still need a few SD60 parts.

Here is another twist for a SD50S. This link goes to a photo album on Utah rails .net. It is detail shots of a Utah railway SD50S. It says it is one of 5 built in Australia.

I know its not the same as the one Randy did, but I found it interesting and just begging to be modeled ;D

I think they were built for Hammersley Iron?

[sarge]

Yup that's what I just read. Here is the link to the measurements he took.

Wrong place for lift rings. Looks like stops, or braces, for the hatch doors when both sides are opened. That way, they don't lie on top of one another in the open position during engine maintenance.

Makes sense to me. "rubber baby buggy bumpers" ;D

A while back Todd asked me if I'd be interested in his SD50-S Project. I accepted and started on it last night. I've made some changes, removed some parts, and started on the build. The sub-bases have been replaced, new nose installed, and the Cannon Cab has been started. (I leave the roof off so I can install the glazing after painting) Thanks for the project Todd, it sure saved me a lot of grief.

This is the way the unit will be built, "as delivered" except for the updated blower housing.

Very cool Randy.....You sure do knock a dent in the heavy modifications quick!

[icghogger]

Scott is right, Randy, you got some serious razor saw skills! Definitely cold-blooded in my book! ;D

[Randy Earle]

Todd has great razor saw skills. He had done all the cutting before he sent it to me. The basis of this locomotive is an Athearn Genesis SD45-2 with SD-50 hood parts. Todd did some machining on the chassis also and installed brass and styrene I beams. There were Cannon & Company Sub Base, and an 81" nose that had to be removed. When Cannon parts are glued together they really don't come back apart. An 88" nose, new sub bases, and Dash 2 cab were installed by me. I have cut new sections for the long hood doors from an Athearn SD40T-2 shell from my parts box to install. I've been working on this and my HH GP-35 this week.

Hey! I found a pic of Norfolk & Western SD50 S # 6505 AS BUILT with the old style blower duct! See...good things come to those who wait, eh?

You were correct Randy.

The SD45-2 is the same frame as the SD40-2. The SD50S was built on this frame. You will notice that the hood ends overlap the step wells at the step well corner. There is a little piece of walkway tread overhanging the step well in the corner and the nose sits on this over hang.

The question I have.

Does the SD50S use the same overall hood from back of cab to long hood end as the standard SD50?

Or is it shorter and if so, where?

[Randy Earle]

Well, I had more photos, but Fotki has absconded with them. (30 bucks a year for what?!!)

The hood is shorter and the door configuration is different from the cut line in my photo back.

From what I understand, the engine room section is the same as the SD40-2. So that leaves the clean air room and the rad section to make up the rest.

It would be interesting to know if the clean air room on the SD50S is the same as a standard SD50?

[Randy Earle]

Here's a page with very good close up photos. It's what I used.

Thanks Randy.

I was searching and just found that page yesterday. Now what I need is to find a good broadside view of a standard SD50 to compare it to.
