Hi folks, here's my final track plan.  I'll have 3 main interconnecting lines with one of the lines serving as a short commuter line as well as a double reversing loop for the other 2 lines.  All my track will be Gargraves with Ross switches.  The curves on the outer BLACK line are 54" dia, the middle RED line is 42" dia and the double reversing BLUE  loop is 36" dia.  I've tried to include a variety of functions to give the layout a purpose.  I purposely didn't include any sidings or yard because I want more room for structures and scenery.  There's a 30" hinged lift for inner access.  I'm too old for a duck under.  Well it's taken me a year to get this far so I'm really looking forward to starting the bench work.  I'm sure there'll be some changes (hopefully minor) along the way.  BTW I'm running conventional and TMCC.  Thanks for looking and please let me know what you think be good or bad.

Loops are great....I love them and my old layout (Run 255) showcased the fact that loops are good!!

My new layout (under construction) is once again loops (folded dogbones, more interest), but loops neverless.

I would try to include some "on layout" storage tracks, longer passing sidings to store other trains to cycle thru the journey around the layout. It certainly looks like that would work in a few places without winding up with a table full of track.

Looks good, keep us posted.

Nick,

I tried a mock up to see what you would run into on the build. Sorry for the lengthy reply, but I wanted to put out forth what I discovered.

  1. The biggest issue is the switch complex - the stuff doesn't fit - may have to move one crossover pair up near the farm. The Ross switches are long, compared to GG.
  2. Using sectional pieces requires a lot of cutting. 1/2 turns to get the gentle loops, fitment cuts for lengths, etc. It may be just as easy to use all GG flex.
  3. You have to decide for table space if the loop around the pillar is O54 inside and O63 outside  or if the O54 outer changes to O42 inside around the pillar. Another reason for all flex.
  4. The angle for lift bridge area needs to be adjusted and the approaches cut to match the angle. Another reason for all flex.
  5. GG nor Ross make an O36. Another reason for all flex. This may be a little tight to bend even with the GG. The O42 could be a tough one also.

Your sketch wandered on the end lines.

Here's a snip of the mock up. I sized the drawing as a background image and built within it. You can see by the rulers it's a 17' x 12' space.

It's a nice design and not an easy build. I really think an Atlas sectional with Ross switches would be a lot easier. They have the radius and the fractional curves for what you need. More $, yes. Less time.

Using the sweeper curve around the pillar really saves aisle space. Creates an interesting build challenge.

I used Ross 11° for the cross-overs of the mains to set a 4.5" center rail spacing. I couldn't decide what would work for getting to the O36 r-loops.

It will be a nice layout. Give it some more thought and planning time. It's almost there.

Hey guys thanks for taking the time to look at my layout design and your encouraging comments.  At 73 I'm old school and not versed in design software.  Graph paper, a scale ruler and compass are it for me so things don't always meet exactly on target.  Thanks again.

Moonman I really appreciate you taking the time to analyze my plan.  Most of the GG track will be flex so I should be able to make the Ross switches work.  Once I get the grid down I'll take a look at the 036 r-loops to possibly change them to 042.  I have a few locomotives that would be very iffy on 036.  I know it's not going to be an easy build but I have nothing but time on my hands.  My wife has been pushing me to get started on this.

Nick,

Ok, the 6 switches for the crossovers and r-loops are now 4 - O42 and 2-O42 wyes. It doesn't mess with your aisle a lot. Move some of your scenery spots and perhaps make a trolley loop where the O36 was. O31/32 will fit nicely or Streets with O21.

It only takes a small amount of table adjusting. You need to work on the bridge angle in front of the door to match the track angle.

I would go with the mixed O42-O54 around the pillar and O54-O63 around that for the O42 mainline.

This is on 4.5" centers set by the 11° crossovers for the main.

Whaddya think?

The pencil and paper are still good. Don't sell yourself short. Look at your result. Nice design for the space. The software just permits a pre-build without doing it.
