new indoor RR needed

[cabbage]

YES I do realise that!!!

The design was simply to show how 9 and 10 feet diameter curves would fit. It is similar to the one both Matthew and I are building for his bedroom -except the two return loops fold over each other to give a lower and raised railway routes. This will give him; his station, his MPD, (and especially) -his Gas Coking plant...

OK -try again...



The blue curves are 9 feet diameter, the red curves are 10 feet diameter, the green is floor. The scale of the drawing is 1cm =1 foot.

Your going to need some duck-unders and access holes there, general rule of thumb is never build anything trackwise that you cannot reach, so access becomes a big design criteria

There is nothing to say that you can not buy some track and just lay it in your back yard and then move it about until it p;eases the eye remember the 10tf rule if it looks good at that distance then you are ok. As for curves remember 2-6-0  2-8-0 and bigger run better on R3 radius 8ft diamiter smaller rad put a lot of torque on the moters but if you are going for 0-4-0 and such like them smaller rad ok. But again remember the size of rolling stock 40ft wagons look a bit naff on radius 1    Hope this helps

OK more Info: current is a 2 track main 10/11.5 with a two bridge duck under. I found a 'L' layout for "O" gauge that use's a 12x16 space and I hoping I can convert it to 16X21 and allow the use on mixed 10/11.5 curves w 9' for sidings. BTW 9 and 10 curves only leave 3" clearance.

Wow your looking to use some wide turns in a tight space for that kind of curviture. If your min dia are 9 or 10 ft, I would suggest a loop of some sort with an operation island in the center and a duck under or lift bridge for access. Maybe a double track 9 and 10 ft dia with a small yard on the inside wall?

An L would likely be limited to some sort of out and back, point to point layout, I considerd doing that but eventually decided it was too limiting, so I am currently planning a loop setup for mine.

CABBAGE, Thanks for your input, however I don't have any 8ft dia. track and I am thinking along the lines of a " L " shape

[cabbage]

Try the good old fashioned "dog bone" layout for starters... Here I have taken your dimensions and produced this using a draw program I got free with my computer in 1996!!!



The green is floor, the yellow is raised benchwork. The curves are 8 feet diameter. There is room in the centre for your table and chairs, and the track should be easy to reach.

OK the DNRR track plan stinks. I need some help with a new track plan. hears what I have to work with: 9' / 10' / 11.5' Dia, 4-#6 & 3-10'dia switch's (3pairs+1), 1-19% crossover can be eliminated ,three bridges-2 at least need be used (2&4 ft). boxs of strait track 3-2-1. For space I have 20'X21' -420sq foot 2car side of 3 car garage. If I had a good easy cad sys (FREE) I would not be asking for HELP. Also I would like to be able to walk in and need a space for a folding table and chair's. BTW the current track plan will be up and running for the Holidays MY WIFE SAID SO. I NEED HELP. PICTURES OF CURRENT SPACE WILL BE POSTED NEXT WEEK.
