The Pennsylvania 4-4-6-4 Q2 Duplex is Running Again!

Beautiful.
1-1/2 inches to the foot and 7-1/2 inch gauge (I think). A popular scale for live steam.
Many years ago I saw an O scale model of this loco built by Bill Lenoir who was at the time one of the premier custom O scale loco builders. His layout had 72 inch radius curves and it didn't like them, lol.

This looks like a really fun hobby.
Here's a link to a live steamers club that I would go to when they are open to the public. It annoyed my Mom because it happened on both her birthday and Mother's Day. Also, here's the first run of a guy's brand new 2-10-4. Note the articulated that passes in front of it early in the video. I know it's a long video, but you get to see a live steamer derail and how to re-rail it.

And the video:

And the video:
.Interesting how they re-rail it. Wonder why it derailed. A 2-10-4 having a bit too long a ridged wheelbase for that curve perhaps?
I think I saw the articulated go by less then a minute into the clip. Looked like a 2-4-4-2.
I also think the pop-off valves went off on the 2-10-4 around minute 10:30. Too much re-railing and not enough chugging down the track, lol.
Thanks for the clip.

I decided to find out how much power the Chesapeake & Ohio 2-10-4 would have if all the dimensions are reduced to 1/8th scale:
Driver Diameter:
Prototype: 69 inches
Scale: 8.625 inches
Cylinders:
Prototype bore (Diameter of cylinders): 29 inches
Scale bore: 3.625 inches
Prototype stroke (Length of cylinders): 34 inches
Scale stroke: 4.25 inches
Boiler pressure: 270 pounds per square inch (psi)
Scale: 200psi
Therefore, using a program found on http://www.steamlocomotive.com/ called 'steam designer' (Note: Program requires Java to work), I managed to find that the locomotive's tractive effort would be:
With friction bearings:
1,101 pounds
With roller bearings:
1,196 pounds
And the speed would be:
18.625 Miles per hour
However, I was wondering if I should reduce the boiler pressure to 150psi. Would this be better suited for this scale locomotive?

I'd think 200 psi would be a bit high for a hobby loco like this but its not impossible. I wonder if these have to have boiler inspections, pressure tests, and certifications like 12 inch to the foot steamers?. A boiler that size at 200 psi could make a fair to middling bang if it burst.

That is impressive! Wow, just WOW. As a PRR fan I wouldn't mind having one of those in my garden!
The boilers do have to be certified to run at places at Mid-South Live Steamers, so I suspect that they have to be certified at other places. I recall that boilers go up to 160 or 180 psi, so I think I'll drop it to 150 psi just for safety sakes.
These are really great videos. I enjoyed watching the guys operate these steamers.
When I was growing up, there was an elderly gent that had a setup in his yard. The trains didn't go far - just around his house and were stored in his garage. Sadly, he died shortly after we moved in and I only saw the trains run once. When his house was sold, the new owner abandoned the tracks and ripped up the ROW. Like the real 12-inch to the foot scale, the ROW is still visible even today if you look carefully.

Then the next questions are:
Who does the certification?
How?
Must be a set of standards so is there some organization that has the authority to say yea or nay or is it up to the individual live steam clubs to set standards and test to them? I'd think a lot of live steamers would move around now and then for the chance to run their locos on different layouts so some sort of standards must apply. Perhaps an association of live steamers?

I wonder if there are fake inspectors?
"Hello, I am Bill McTrustworthy, and I am here to ste-I mean certify your loco. I will need to take it to my hous-Um, er inspection office and neve-I mean return it shortly afterwards"

There's the International Brotherhood of Live Steamers (IBLS), and they have standards for wheels, couplers and safety chains, and track.
Here's a link to their wiki regarding how to certify your boiler:

Also, here's a list of live steamer suppliers and retailers:

Questions 1 and 2 are easy. 1.Bill McTrustworthy 2.by taking it to his "Inspection office" :hehe:
Interesting links there - thanks.
When I first got into model railroading and all that the only company I remember was Little Engines. I see they are still around but so are a heck of a lot of others. The hobby has grown by leaps and bounds.
I'd imagine you entire need to be an accomplished machinist with a good workshop or wealthy enough to have someone build it for you (but where's the fun in that, lol).

If you want to see some of the interesting things you can scroll thru the 'photos' section of the Mid-South Live Steamers website: http://www.midsouthlivesteamers.org/
To see a model of Nickel Plate 765's sister, Nickel Plate 757, go to the 2014 Spring Meet
To see the trains featured in the YouTube video, and a train you will never find me in (which I call the 'Girl's Train, for obvious reasons), go to the 2012 Fall Meet
To see how some people decorate the front of their diesels, go to the 2012 Spring Meet
To see a guy's model of the Southern's 4-6-2 Ps-4's, go to the 2009 Spring Meet
To see the guts of a diesel, go to the 2008 Spring Meet
To see a guy's 'tow truck on rails', go to the 2007 Spring Meet
To see a guy's 'private hi-railer', go to the 2005 Spring Meet
I'd like to know what you think about those pictures and the rest of the pictures there.
