Yeah, and she can kick your butt, too![:D] LOL.
Kari blows Scottie's doors off. Not even a close race.

P.S. Rumor has it that Scottie plays for the other team, if you know what I mean.

In the tradition of the actual show, I would like them to do a Gomez Adams and cra***wo hiball steam engines (not mine)[;)] head on in a tunnel. They could see what would the initial impact would be and then, as is usually the case, they could rig it with explosives and repeat. Come to think of it, I don't think I want them to use my layout or house either.

I would like Mythbusters to dispel the myth that HO is better than N, cause I know for a fact it isn't !!

Tiresome, perhaps, but I too would like a "Busted!" or not on track cleaning methods...

Shouldn't be a problem to get them to do it... Bergie can just fund the show with his Walthers/Kalmbach (Walmbach?) fortune...

Forced to pick something else, I would fall back on the old "does twisting the wires on a DCC bus really prevent crosstalk, and just how long a bus can you run without affecting operation anyway?" question.

That's the first thing that popped into my mind when I read the title of this thread! And I've never done it with a 9-volt battery either.

Jesse, we were both off. I was doing my math hastily on the back of an envelope. I used 55,000 pounds for the hopper load instead of 110,000 pounds. Ten loaded two-bay hoppers weighed 1,507,000 pounds (10 * (110,000-pound load + 40,700-pound light weight)). A WM H-9 weighed 310,000 pounds. Result = it could pull 4.86 times its own weight up the Black Fork grade, not the 3.09 I originally stated. So on a weight basis it is out-pulling my model by 23%, although on a number-of-cars basis, my model outpulls the prototype by 80%.

[Budliner]

now I get it!!!

One measured example: my brass Western Maryland H-9 Consolidation, 16 ounces including extra weight but excluding tender, can pull 18 55-ton hoppers with model coal loads up a 3% grade without slipping. The same loco was rated for ten such loads up the 3% Black Fork grade by the WM. With a load of 110,000 pounds and a light weight of 40,700 pounds, the real thing could pull 3.087 x its own weight. My model, pulling cars weighing 3.5 ounces including loads, can pull 3.938 x its own weight.

On the other hand, an N&W Y3 2-8-8-2 was rated at approximately 150 loaded USRA two-bay hoppers on level track. I don't have enough hoppers to make the test, but I guarantee you that this is two to three times what my Powerhouse metal or LifeLike P2K plastic can pull.

By the way, OUENGR, although the issue of scaling weight doesn't affect the methodology I used in my comparisons above, surely your position that weight scales to 1/87^3 is correct only for solid shapes of a uniform density?

Methinketh thy math is auf abit -- lol.

10x 55-ton hoppers = 10x (55x 2000) = 1,100,000 pounds. The proto loco wouldn't have max TE at its lightweight, but using your figure of 40,700 pounds, the prototype would be pulling just over 27.027 times its weight.

In HO, your 16 ounces (16 oz = 1 lb) translates to (1x 87x 87x 87) ... or 658,503 pounds. If your cars scaled to 110,000 pounds apiece, it is pulling 18x 55-ton hoppers = 18x (55x 2000) = 1,980,000 pounds, or just less than 3.007 times its weight. Pound-for-pound, the proto is pulling 9 times as hard.

However, 3.5 ounces translates to 144,047.53 HO pounds, so your 658,503-pound loco is pulling (18x 144,047.53) = almost 2,592,856 pounds, or 3.9375 times its own weight. (Note that, here, my numbers agree with yours). The prototype still does better by just over 6.864:1.

Another way of looking at it, though, is that if your cars were scaled back to 1,169.32 grains (7,000 grains = 1 pound), they'd scale to 110,000.1 HO pounds, and your loco would be pulling 23 of them -- even though the prototype was rated to pull only 10!

Ain't math great?

Regarding density, I think that's the whole idea of taking the cube root of the weight of the prototype. In other words, that automatically compensates for variations in density.

If you were simulating gravimetric centers, polar moments of inertia and things like that, then you would of necessity be concerned with the distribution of the weight within whatever you were modeling (for instance, a railcar or a locomotive).

Accurate such modeling could in practice be both costly and complex, but the calculations are extraordinarily simple.

HAPPY RAILS!

You read my mind.

[davekelly]

Wow, did you guys read/hear that? Bergie is independently wealthy also!!! I guess you can do that when you own Walthers.

[:D]

[Bergie]

Yeah, and I only work because my doctor says it's good for me. Right...

[:)] Bergie

[davekelly]

It's my understanding that Bergie also own Horizon/Athearn/Roundhouse and is actually Al Kalmbach come back to life.

Bergie owns walthers
wow I did not know

Of course, it wouldn’t be a very exciting episode because it would only last about 30 seconds. Trust me, regardless of what you may have heard, we’re not the same company.

Well, true, but you omitted the key word "yet" from the last sentance... [:p]

Whatever you say, Phil.

Just joking!

They actually have done a rail related myth. The myth was a drunk guy whizzed on the thrid rail of the NYC subway system and was electrocuted to death. They went to the Hunter's Point Naval Yard which was the home of the Golden Gate Railroad Museum to test the myth. In a few shots one of the SP Pacifics that was stored there can be seen.

The myth was busted. Seems that the "stream" was not steady enough to carry the charge back to the body.

This was a PK (Pre-Kari) show so, they rarely show it anymore and it is not that interesting to watch:-D

[Budliner]

ya when they touch it

[davekelly]

Would love them to explore the thought that "stuff derails more when non model railroader guests are present." I think this is not a myth - but pure fact. I, however, do not have a lot of data to draw on. It's pretty much the truth on my layout!! Anyone else?

Nuff' said!

the best part of mythe busters is when the blow up buster

I dont think my house insurance would cover them while they were here. Or me for that matter[:o)]

Rail5 (and others):

For the heck of it, here's the offical Discovery Channel Mythbuster's site:

http://dsc.discovery.com/fansites/mythbusters/mythbusters.html

Check the episode guides, they give a summary of each episode - since Model Railroaders tend to be into engineering and technical matters, there might be some segments of interest to you. I don't believe they have done any railroad-based myths (well, I don't remember any), but from time to time they do myths at abandoned naval bases in the San Francisco area, and you can see the former base trackage winding around here and there (particular noticible in the high-riser crane catapult that has been mentioned before.

I like it almost as much as the erstwhile 'Junkyard Wars' (remember that show, before they mucked it up as Megawars in the US - I believe the UK still has the original premise airing...)

[Budliner]

I would like to see adam make a ho steam and pump it up till it exploads and see if the house is still standing



lol

[timthechef]

Nothing!! They like to blow things up too much!

Thanks, PCarrell, if its on TV and its not the NFL, I am clueless. Usually I can extrapolate from the title of a show, that people are talking about some TV show, but not this time.

OUENGR, using your formula, at a rough glance it appears to me that our locomotives and our full-length passenger cars are generally two to three times heavier than scale, my 55-ton hoppers are nearly spot-on, my 40-foot boxcars are 50-100% heavier, and much of the modern freight equipment is pretty close.
