Okay, there is more space than I thought.  Apparently, there can be aisles on the outside of the layout all the way around.

Thanks, Bear. I appreciate the effort.

The first drawing baffles me somewhat in that it just seems to be a sort of deformed oval. What's the advantage over prior drawings?

The second drawing is very similar to Bear's earlier drawing, and I remain convinced that it is superior in all respects. The earlier drawing made provision to choose to enter or bypass the peninsula, adding interest to the layout.

It seems to me that a square footprint limits the opportunities to add interest to what otherwise becomes a circular layout for all practical purposes. While the overall square footage is decent at 200 square feet (14' x 14.5'), some sort of rectangular footprint would provide more opportunities for sidings and spurs. I think that is what Sheldon had in mind when he mused over a possible 26' x 9' footprint.

I am having a difficult time visualing this proposed Z-layout. Can someone draw it?

I thought I could but…

it does sit off the two walls by 2 feet.   

If that's the case then why not JaBears 2nd plan modified to be a Z.  Return loop in the NW and SE corner, wide benchwork along the north and south sides and diagonal NE to SW middle bench.  You don't operate it from the "inside" you operate it from the "outside".  All the benchwork has a backdrop down the middle with a scene on either side.

26' x 9' would make a much better layout. 

That would be a question for the OP to answer. Is he committed to a 14' x 14.5' layout in that specific space?

Bears first though of it being in a bigger space is correct.  It sits in a 26 x 26 building. 15 x 15 is the dedicted space for the layout area.  rest is workshop and storage.     it does sit off the two walls by 2 feet.   Stands alone,no wall supoport.   The configuration can be shifted around as long as either the generl square footage of the areas are maintained or the layout design is smaller.  doenst have to fill that whole area

You get continuous running with no duckunders, you get visually "pure" scenes.  If you make the benchwork on the straights a series of sections, one for each "side", then the layout could be disassembled and possibly reconfigured as an around the walls layout later.

Everybody will tell you an around the wall layout is better, but you aren't doing that in the first place, so it doesn't matter.  You are building an island, leverage the strengths of an island layout to your advantage.

 

 I agree!  With no walls, I would also do a Z shaped, self-standing layout. Bonus: if you move, you can probably take it with you without too much damage, if you plan it that way. A coal mine at one end (in montainous scenery), and industry/yard at the other end. I wish I had space to do that...

Now, and don’t ask me why, I got the impression that the layout area was part of as larger basement and had access on at least, two sides, as peninsulas are space gobbling devices and require such access.

I am not sure that we know whether Shane has access to all sides of the proposed layout or whether one or more sides of the layout are up against walls. I re-read his original post and his subsequent replies, and I see no indication of full or limited access.

That makes Bear's first proposed track plan superior in many respects

Gidday Rich, I wish I had your confidence!!LaughLaugh
 
I drew design number one, the primary reason being the reason of elimination of the duckunder. Now, and don’t ask me why, I got the impression that the layout area was part of as larger basement and had access on at least, two sides, as peninsulas are space gobbling devices and require such access. The reason I did not include a loop in the middle peninsula is that I wished to keep the 24” radius and 2’6” aisles.
 
Design number two came about when I considered that it may actually have to fit in an actual room!
 
I have deliberately not filled the dots, because as others have pointed out there are many possible variations, all worth consideration.
 
It all depends on what Shane regards as important.

Not doing duck unders since I do have back problems and now slight balance problems from a stroke.   so lift sections or no sections at all.  

That makes Bear's first proposed track plan superior in many respects. Add that pair of crossovers that I suggested to reverse the direction of trains, and you will be off and running...trains.

Duck unders are never a good idea. Just because you are in perfect health dosn't mean you can't step wrong and have a wobble for a few weeks, had that happen twice in the last 5 years, first time I could barely walk for a few days and I can keep up with the 20 year olds on class 3 trails. Oh and the stepping wrong happened walking down a concreat sidewalk that first time.

 

Well they don't have to be duck unders, they can be lift outs, or lift ups, swinging gates like the one that appeared in a "different" magazine a year or so ago. I am seriously consdering that for mine.

The well published Severna Park Model Railroad Club which has appeard in MR 5 or 6 times in the last 60 years has a duck under, no casualties yet..... even with the public coming in for open houses.

Radius of the curves is a big factor as well, as others have mentioned. With 6 axle diesels, you need, at minimum, 22" radius. Sheldon would argue for more, and he would be right if you have long passenger cars or freight cars.

The point I am making is that if you want a loop for continuous operation, then doing that without a liftout involves large return loops at least 46" wide. That creates reach problems. For that reason, the liftout option, with track running along the walls with 24'' shelves is preferable. Otherwise, you need to think how you will reach that darn loco that derailed in the loop, against the wall... It's also easier to build scenery when every inch of the layout is easily reachable.

The area I. Question has mostly single track and for most of its time it has been that way.   Might have been a few double track areas at one time.  

I did have double track at one time.  .  I do see the advantage.  

I take it the general consensus is the original isn't any good.

I agree with Sheldon.  A plan for this size should be around the room with a duckunder/liftout at the entrance.  Peninsulas would probably not add much to operations and risk just being in the way of better elbow room.  If you want to store stuff underneath the layout...skinny aisles make it hard to stoop without bumping your head or shoulders on the way back up.  Maybe one side could have a little bump-in for a slight curve on one of the four walls.

I would have a town from 7 oclock to 11 o clock and then another from 3 oclock to 6 oclock with the liftout in the SW corner dead space.  Operate it point to point style but simply run laps around the room to build up simulated distance between towns.  Its important for a small layout to have that continuous running feature. 

A double mainline would allow the train to use the outer loop for gathering lapping distance and then cross into the inner loop to pull into the stations.

And then there are the times you simply want to run two trains in opposite directions just because you can.

The plan could also have room for two or more staging tracks along a wall, possibly hidden behind a partial ridge.  Another bonus of being able to have wider shelves since there wouldn't be a peninsula.

I can see potential in Bear's last design.    

 

 

I still like Bear's first design, with or without my suggested modifications. A lot more interesting than the second design which is way too basic for me. And, there is no need for a lift out on the first design.

 

I also like the idea of a double mainline.

Rich

 

The problem I see with Bear's first plan is there isn't a convenient long enough straight section for a decent yard.  Bear's second plan allows for that along the left wall.  You could also add a staging track or two behind the yard hidden with a low backdrop.

First off if you want to do a continuous run, fiqure out your min radius and find two places in the room that a circle of that size fits. Then connect the two any way you want and the work your other stuff into it.

 

I will suggest again that being inside the circle and avoiding "balloon" loops is much more effective in a space of this size and well worth the duck under/lift out compromize.

If you want staging or a longer run, go twice around hiding some parts of the run.

Our selectively compressed curves look better from the inside. 

Continuity of direction, left is west, right is east, is maintained making operations more logical and simpler.

And there is no real estate "inside the loops" that is hard to justify or use.

Hi there. You definitely have room for a single mainline with 2 return loops at each end for an open entry into the room. The question is: do you want a double mainline or not. A double mainline adds to the fun and is quite dooable with a liftout.

A double main would completely change the feel of the layout.  

 

 

Given the footprint of the proposed layout, there probably isn't sufficient room for a double mainline, but I still like the idea.  Stick out tongue

Double track does not take much extra room. Being able to go 2" larger on the curves is the biggest space consideration for double track. 

A layout this size would definately be better in double track.

A double main line would fit if the curved track on the bottom left extends to the liftout (Dr. Wayne has done this, I can pull it up if needed). Or if the liftout is moved a few feet on the right. My train room is 11'X7' and I have a liftout with two mainlines (22" radius). It's tight, but it fits and it is perfectly functional.

A double main would completely change the feel of the layout.  Not saying it can't be done or isn't appropriate, there are lots spun off secondary routes of the PC/RDG/LV in the east that were double track at one time.

As far as two levels goes, one coud easily split the line at some point and have the portion on the center peninsula on one level and one of the two spurs at the bottom on a separate level.  Very common in SE PA to have multiple lines in the same valley on different level (most likely different railroads that could have been spun off by CR.

A double mainline adds to the fun and is quite dooable with a liftout. I have a liftout - not that hard to do (If you've never built one, I suggest you do a search to see what are the best practices).  My liftout is hinged, has two lines of track and is most often in an up-right position. You'd be surprised the number of times you go in and out of the train room with materials in your hands...  Maybe do a coal mine (in some hilly terrain) at one end, and build an industrial site at the opposite side, with one or two passenger stations in between.

I'd leave space in the middle for a comfy chair or two were you can sit, watch two trains run in opposite directions, and sip your favorite beverage. Note: a track that is positioned too high cuts down your visibility if you are sitting in a comfy chair.

I forgot to mention that this is central pa and that is mostly smaller branch lines, regonals and shortlines.     The only 6 axles that run now go from the yard to the quarry.  Athearn and BLI untis.   most of the fleet are 4 axle.  trains usually around 10 caRs but can go to 14.    Modern era.   layout sits at about 45 inches off the floor

I can see potential in Bear's last design.    Any body have ideas on something smaller or possible double level?

I like your design. However, I might suggest that the OP do a mock up to see if the aisle widths are adequate. If the OP will be the lone operator then I don't see any problems, but if he wants to have guests then everyone had better be pretty skinny, or he needs to narrow the benchwork in a few places to allow operators to pass each other.

I quite agree Dave. By having a duckunder in the plan Shane posted, I’m working on the assumption that Shane is not too concerned about guests: and that he wants the ability to have a continuous run but with lots of switching.
 
With revision 1, I’ve drawn what I’d more likely do if that was the space, I had to work in. In the switching areas I’d probably cut my minimum radius to 18”, but then I’m only running 40 to 50’ rolling stock and 4 axle locomotives, or short coupled steam locomotives.
