That mini-layout is superb, no excuse now for not having any space. Great idea.

 

My girlfriend says like a railway running round the Millenium Falcon!!!

Still can't figure out the track layout on this cracking layout,can any one help?

 

I tried sketching it in Paint,but you don't want to see it. I think it's a figure-8, folded over on itself with one loop inside the other. A single slip or pair of facing switches with a crossover between their diverging routes would improve operations alot.

So in the above photo, the tank car is on the back of the train with the UP switcher on the front, and a loop inside the buildings. The outer loop runs round the outside.

Thanks,still can't figure it out,do you think it's sectional track? Need to see it as a plan,would like a bash at something like this,cheers Rob.

 

 

Dear Robbo,

 

It's a really quick n ugly MSPaint schematic, but does this help?

Red Lines = track (suspect average 15-16" radii, with tighter sections)

dashed red line = track hidden inside the building (suspect relatively consistent/smotth 12" radii)

Brown lines = approx outline/footprint of the building

blue "tunnel portals" = where track enters/exits the building

 

Obviously, the layout is built on a 3' dia circle benchwork, not square as implied by the drawing wink.gif

 

No, I do not think it's sectional track, as the radii of the hidden trackage is around 12", as is the "kinks" leading into the outer legs of the diamond crossing. A close look at the turnout around the back of the layout seems to suggest it's a Atlas item, and Atlas also do small/short diamond crossings. Ergo, I suspect the trackwork is either code 83 or 100 Atlas flextrack and the above-mentioned pieces.

 

Happy Modelling,

Talk about 'thinking outside the box' !! Nice layout, you need a loco that can run reliably at low speed all day, - that rules out anything from Lima with the old pancake motor then!! I was just thinking a British version would be nice, with a class 33 and some short 4 wheel vans and maybe a few cement or salt wagons.

Dear Carboot,

 

When I saw the double-headed Athearn SW1500s, my first thought was

"I'd hate to see the thrashing the drivelines /shafts are getting"

 

If you were building locos _specifically_ to run on such a layout, replacing the stock mech with an under-floor drive like a pair of 27:1 ratio Black Beetles

 

http://home.waterfront.net.au/~sem/bbeetle.htm

 

would be just the ticket. Then all you'd need to worry about is whether the coupler swing between the locos n cars would become the 'weak link"... biggrin.gif unsure.gif

 

In terms of UK stuff, I'm not sure that any of the 0-6-0 diesel shunters would make it around the 12" curves, unless the centre wheels were blind/flangeless. That said, I'm seeing some nice smooth running out of the newer Bachmann Branchline stuff,

 

so smooth/slow mech + flangeless centre wheels + small UK 4-whl wagons = smile.gif ???

 

Hmmm....

Thanks for sketch.Rob.

 

 

Dear Rob,

 

No worries, glad it helped. It's actually a deceptively simple "folded figure 8"...

 

As mentioned above,

replacing the diamond with a double-slip would render the inner 12" circle as a pair of "back-to-back spurs",

and the outside 15" circle as the "mainline",

with a short/sharp "reverse-direction" kink thru the dbl-slip...

(but would increase the "switching/shunting" factor by a few notches wink.gif )

Dear RMWeb fans,

 

This just broke, YouTube posted of this fantastic little layout

My HO scale layout uses a minimum 12" radius, and i've found most cars up to 50' length are fine, although coupling them on a curve is an issue. Loco wise, i've run Athearn locos up to a GP38 (including a SW1500), CF7, Atlas S4, Bachmann 44, 45 and 70 tonners, plus a few brass interurban locos.

 

I once built a figure-8 test track on a 4' x 2' sheet of MDF, and played the same "train chasing it's tail" game as on the video..!! The tightness of the redius is less of a problem, the main issue being any sharp kinks or "S" curves that the trucks or couplers did't like.

I think I would put the line a bit further out instead of using a slip, the reverse curves would be nasty, you'd end up handbuilding a "sharp" slip and embedding the slip in the road would be hell anyway...my suggestion would be something like:

 

post-6762-127903280219.jpg

 

Gives you a bit of spare track to leave cars on whilst switching, if you didn't have too many cars and had each door as a different industry you could do origin-destination traffic, pick up from one location, run round the train, deliver to the other, run round the train...etc etc

 

How about r/c or otherwise moveable vehicles that you have to move out of the way before switching the industries.

But I think you've still got the problem that any continuous layout, even with a 12 inch radius in HO, is going to stick out into the space in such a way that the room needed to tend the thing with non-compressable human bodies is going to double (or more) the actual space consumed. Especially for street running, a shelf layout is maybe even better suited to switching.

A friend has built a similar sized layout for a minimum space competition, and i'd have to agree that such a finished project can be quite bulky. We did suggest making an outer covering from old carpet and rolling the layout into exhibition halls on it's side..!! :

But then again, this type of layout is more of a fun side project than the serious main one. Imagine either of these with a glass lid over the top, for use as a coffee table...
