Arizona Grand Scale Railway Society

Post by Glenn Brooks » Sun Dec 19, 2021 8:35 pm

Hello All,

Very excited to announce, Scotty Brooks and I are organizing a Grand Scale Railway Society in Pheonix to build and operate a 15” gauge live Steam railway division at the Sahuaro Railroad Museum - parent organization of the Maricopa Live Steamers. All the resources on are hand to commence laying rail mid January, 2022 - pending Museum Board approval. RR members will be able to build and run their own 15” ga equipment, or operate the Museums locomotive.

If you are interesting in joining, or participating in building the RR, or supporting efforts down the road feel free to let me know off line or via PM.

Thanks much,

Glenn

Gosh darn, that's a bit of a commute for me. Just out of curiosity, what is the minimum radius going to be? At some point in the future I will be looking for places to run my locomotive, once I get it built. 100ft minimum sure would be nice.....I could squeak by on that.

Hey Nyle, how far along are you? Pics would be great. Our short line might be 60 or 70’ radius. Probably have to rethink that in the near future- like Tuesday when we review our ROW plan. We do have a possible 3 mile route in mind - far in the future, but possible, that could be 100’ R.

So just ship that bad boy out here and leave it to play with in the nice warm winter months. - sunny and 75* today - mid day.

Oh, I am not close to being done by any means, regular work keeps getting in the way, but I have to think into the future. I'll shortly have a machine up and running that for the most will be dedicated to the production of my loco. Eventually I'll start a post of my build in the Grand Scales forum.

Well, good news! The Board approved our 15” ga RR proposal this morning. A primary objective is to build a member operated and maintained railway - and encourage members to build or restores then operate their equipment on the railway - similar fashion to the live steam club model- only hosted as an historical exhibit through the Museum.


Phase 1 is a short 650 LF freight yard outer loop. - black trackage in the attached photo. Phase 2 be a mainline extension, and Phase three (yellow) an additional point to point extension out to MLS and back. A 2 mile “transcontinental route” around the periphery of MLS will extend Phase 3, as we develop sufficient community.

The RR will be an operating, 1/3 scale historical interpretative exhibit, focusing on Arizona railway development since the first 1886 transcontinental railway route opened up through the Sonoran desert.

Here’s the plan, as of today...

1/3 scale ...? What: flange, check gauge, back to back, etc.? A 5/12 scale loco (3' narrow gauge on 15") , and also a 3" scale (3/12) loco, will probably not run through turnouts and frogs made to 4" scale (1/3) track standards. There isn't much room to play with different scale in those track standards.

We’ve been reviewing that, so far leaning towards the 5” scale standards, flanges 1/2” x 11/16” wide.

Back to back is 13 5/8” on everything, so 15” gauge with 12# rail isn’t a problem.

However, We have equipment with wheel profiles at 1/4 scale, (3” scale), 1/3 scale (4” scale) and 5” scale. So it’s a delima.

We think most hobbyists will want to build either 3” or 4” scale - which is also the lion share of amusement park trains size. So looking for advice and operating knowledge running 3” equipment through 5” switches. Any thoughts?

Jut starting to build switches this week, and would like to nail down standards discussion before we get to deep in the project.

Thanks
Glenn

I responded in the other post, I think to keep it such that you'll have interchange with other 15" tracks you should adhere to 15" gage standards regardless of scale. There are large dimensional differences in the wheel profiles between 3, 4, and 5" scale, one isn't going to work on the other.
That said, there are so few 15" tracks that if this equipment will never travel, you can do what you like as far as adopting a spec.
It doesn't even need to hold back track laying, just hold up on mounting the guardrails until it's been finalized.
