is there an ho scale tgv? Yup there is made by lima I think it’s out of production.
is there a ho scale 0-2-2? Yup there is but I think it’s out of production to.
why did athearn put traction tires on expensive locomotives? so it can continue to pull the train uphill.
the formmula for converting drawbars push/pull to the number of cars the locomotive can pull** % Math time I will post what math I did along with instructions.
why are steam locomotives more money then diesels? More parts and detail.
what does the pcm big boy look like on a 22" raduis curve?* “Toy like”, “ridiculous”, “it might be impressive because something so large can go around such a tight curve” I would like a picture of this so I can see what I think.
smoke or no smoke for steam engines? No smoke; messy, smelly, gets track dirty, potentially hazardous.
*picture?(recommended)
**example?
% let’s say that all the rolling stock on question is 40’ box cars.
I’ll search for the tgv the only one from walthers is in n scale.
hmmm maybe I’ll try a web search instad of a froogle search.
I would if i had enough room. but more than ten cars the train starts to look like it’s chasing it’s tail.
Anyone know what issue? if not I’ll have to buy some cars that are the same lengh or do som measuring.
Aha! that’s why
Well I know that but depending on how horrible it looks if it doesn’t look to bad I’ll hve to wait for more room to enable bigger curves.
So it makes the track dirtier? [xx(] then no smoke with dcc(coming after kato sd90) Personaly I think in the videos and pictures that I’ve seen with smoke the generators don’t put out enough for ho scale but enough(barely) for n scale.
yes like the bigboy. just out of curiosity how much does the athaern big boy weigh? same for the pcm one.
does that mean the curves? because currently I don’t have any straight and level track so the test will either be done on a roughly 3% grade or a 22" radius curve.
know about the extra detail. Does anyone know if in the prototype if steam engines are more expensive than diesels.
Picture?
answered no smoke for me especially since I have 3% grades and my layout is in a garage with an unsealed floor.
The original 7 questions:
1). HO TGV: Yes. I remember seeing them when I was a kid at KayBee Toy & Hobby shops (back when they sold model trains…sometime in the mid-1980’s, early-90’s). They used to sell Life-Like and Bachmann products, so it was probably either one of them. It wasn’t the whole train, BTW. Both power cars (only one powered, IIRC), and a couple-three coaches. Every once and a while I see them in the junk bins at the local train shows.
2). 0-2-2: Never heard of one. A 2-2-0 would be more likely & dating back to the 1830’s, but that’s about it. RR’s quickly realized that 4 drivers were superior to 2. Not to say that there wasn’t a 0-2-2, but they weren’t common, and they’d be so small I don’t know how you’d power them. Even the DeWitt Clinton is an 0-4-0, and that hauled stagecoaches on flanged wheels. BTW, quick trivia question: If an 4-4-0 is an “American”, what is a 4-2-0 called? A “Bicycle”.
3). Traction tires: At my club, we’re building a 6300 sq ft. HO layout with long trains (25’ long trains are not uncommon). And while it’s realistic to keep adding diesels to make the train move, most steam powered trains only used one steam engine. Throw in some grades of 2.5% to 3%, and you need all the power you can get for steam.
4). Drawbar pull: The general rule of thumb for locos is that approx. 25% of the weight of the loco is the amount of force available on the drawbar. So if an engine weighs 16 oz., it can usually apply 4 oz. of force to the drawbar (assuming all wheels powered, track and wheels cleaned, etc.). Now as to how to convert that number into cars? You need to determine the “ruling grade” of your layout. Usually the highest grade on the sharpest curve. Then you need to measure how much force is required to move a certain number of standard cars u
Grades yup I see a reason though I have a locomotive that the only driven wheels are traction tires it pulls/pushes 7 cars without wheel slippage on flats and up grades of 3%
math time! [:p][xx(]
that’s a long run and my oh my locomotives are expensive.
good point point hmmm.
ventilation = no problem oily residue and bad smell?[xx(][xx(][xx(]
The bidding has ended but it appears that at least someone made a model of Stephenson’s Rocket, if unpowered. Try searching for specific locomotives, like Tom Thumb or Novelty. Pretty darn small, it’d be a challenge to model in a powered form just because they were so tiny. One might kitbash one of those little “gandy dancer” power truck things.
Aha! thanks for the link. and the search tips to www.froogle.com I go . and I found the ho scale tgv made by lima one is currently on eaby going for about $50. But it’s out of production and does anyone know of one currently in production?
because (1) it’s cheaper than buying a bigger motor (2) some people like to run on 3% grades.
There is none. It’s made up. What are the ‘rolling’ characteristics of each of your cars?
More parts.
“Toylike”, (you asked).
1.
Not for me. Makes tracks slippery
1.
O.K., Lets: IM 40’ cars roll better than - say Walthers, and some others.(Better sideframes), therefor they pull X more cars on ‘flat’ terrain - not grades.
Want to know weights? - Ask the manufacturer.
Your questions are ‘academic’ (not ‘how to’) and combined with your spelling tells me you are a very young person. ‘Academic’ questions (7) are too often ‘what if’ types that generate 7 MORE speculative questions, rather than address any existing problems.
I have one Q. I KNOW you don’t have a $500 Big Boy. How about a layout with 22" curves??
Yes I am young, my spelling is usaully better but lately it hasn’t been.
No I don’t have a big boy, yes I do have an uncompleted layout with 22" radius curves on the outer track. No pictures because I don’t have a digital camera or access to one. But unless you want to see a funny green bue color of extruded styrofoam with code 100 track and wood roadbed there isn’t any reason to post pictures anyways.
