Folks-Sorry if this topic has been covered to death. I'm a longtime HO modeler who is planning my first On30 layout. I will be building something with sharp curves, running small equipment like bashed critters and Porters. I like the somewhat whimsical look of the small rolling stock (ore cars, etc.) running on small radius backwoods trackage.Most of the "real" O scale track plans I am finding are really big and I want this first effort in On30 to be reasonably small, maybe even the dreaded 4X8. I understand the gauge is the same as HO, however, I know that the structures, scenery, etc. will need to be twice the size in most cases (maybe cheating a little). So my question is this: Is it safe to build something like the attached HO track plan for On30? Other than having room for structures are there any other issues I need to deal with?Am I missing something? I usually am!Stan

You said it yourself. Those HO plans afford for tiny structures and other features. A pal of mine designed my initial track plan for my On30 layout (I never intended on running ‘shorty’ anything though and while well-intentioned, it didn’t work out at all as he later admitted he was, “writing down in On30, but still thinking in HO.” The plan had to be scrapped and we just laid track in a highly abridged version of his original idea.
If you use that plan, count on using half those structures, if even then. That’s awfully tight for anything in O. No matter how tight the curves or short the cars, a structure is still going to be twice the size of its HO counterpart.

While the track gauge is the same the scale is almost twice larger. So track centers will have to be larger also to fit the physically larger equipment. Also structures will be actually almost 4 times bigger (twice the width and twice the depth). It is possible to have a great On30 4X8 layout, but probably is a lot easier to start from scratch than trying to rework an existing HO track plan.
Check all the postings by our On30 modelers for inspiration and ideas. Great stuff there.
Jose.

Jose.
And remember vertical clearances at those bridges will have to be greater; three percent grade on HO plan to gain height for those bridges could well need to be eight percent when converting same space to On30 clearances. Got cog rail?

Editing my original post...not sure how well that layout would work in 4x8...might be possible but it won't be easy. Still, take a look at this 2x6 layout for what's possible if you're prepared to shoehorn everything in...
For some reason I can't post a link to Youtube...but suggest going to youtube and search for a file entitled "Great Little 2' x '6 On30 Layout"
One way to save space is to scratch build your structures...you can cut out a lot of unnecessary space that O-scale kits just don't offer.

I don't think you could build this in HO, much less On30.  Those old track plans looked good on paper but often impossible to build.

The great little On30 layout can be found here.

Thanks for the link, Helmut. I have seen this vid before and the little pike is really neat. My little layout (2' X 4') is On20 (runs on HOn3 gauge) and while it doesn't have the fierce grades and over & under thing, it is most pleasing and relaxing to run...just watching it run is a a hoot. I have 10" radius curves and heard all the BS about the MDC HOn3 Shays not being able to curve like that but mine does, maybe because I threatened her with a razor saw!

Nice!. Clearances are so tight that an extra coat of paint on equipment would make them hit the rocks!.

Hi Stan :wave:



I would tend to agree with all the comments made so far.

I think an HO plan could be an 'inspiration'...

... but perhaps simpler ones, like the classic 'Gum Stump & Snowshoe' for example.



Your minimum radius is really important.

A Forney needs 22"

A Shay 15" or more safely 18"

A Mogul should do 18" as well.

Porters ... well, I've heard all kinds of stories ! :shocked:



I think your choice of locos & either shorter/longer rolling stock is a key factor.

The radius they need & that of the track parts you use, will dictate a lot of a trackplan.



How's the thoughts on it going Stan ?

What rolling stocks are you liking the idea of using ?



:moose:



Si.



No matter how many trackplans I see or draw ...

... I still think I can get more in than is in any way realistic ! L:


I drew some simple 'looping' formats a while back, which cover most basic possibilities.

Radius can be anything you want, the background grid is not to scale.
