Half Loop Radius

[Bayway Terminal]

What demensions should the bench work be if im planning a 24'' or 36" inch elevated curve connecting from an existing single lead track ?

The planned track extenstion will be exiting an existing flat surfaced yard area, and this initial layout expansion will start by using sections of flex track with no turnouts involved, just an elevated half-loop radius / which will expand my shelf layout eventully by another 15 ft or more, but first i will need to make this right turn due to a basement wall. 

Note: At the very end of the planned 15 ft. shelf expansion i'm planning a 24" or 36" circle loop.  Bayway Terminal NJ

The width of the benchwork needed is twice the radius plus the width of the track and ties, plus clearance and safety margins to walls or aisles.

Right turn of 90 degrees or 180 degrees? That is are you turning 1/4 of a circle or half a circle?

To make a 90 degree turn from your yard to an adjoining straight section can take a lot less space than you might think. 

 

 

It would help to understand what you wish to accomplish if we had a photo for reference.

 

The benchwork, especially for a 90º curve, doesn't have to be much wider than the track itself, although if it's in a corner of the room, it would make sense to also fill the space between where the walls meet and where the track curves.

NOTE: This is not my area of expert knowledge, so when Byron responds and tells you what I am wrong about... listen to Byron.

I assume you are in HO scale, and what you are planning is a return loop at the end of the layout.

These things are space eaters. The drawing below shows how much space is needed for 22 inch radius curves in HO scale, you can see it is almost 4 foot by 8 foot. If you put one on each end, that will be all of your 15 foot length. On one side only, and you lose almost half of your usable space.

I hope this helps a little.

Respectfully if I clould learn how to post photos i certainly would, Bayway Terminal

Your return loop plan will be useful, but will not occur until the very end of the layout expansion, first i need to make a right turn coming off an existing out-side lead for out - bound traffic. The existing inside lead track is 22 inches opposite the out bound described, and the overall out-side dimension of my shelf layout is 36 inches. This being the return loop connection for inbound traffic back to the existing industrial yard will have to be taken into consideration as well. Bayway Terminal NJ

90 degrees / but gradually elevated. I need to turn a corner due to a basemmet wall in the way. , i would prefer a 22 or 30 degree radius curve . Bayway Terminal

Hope this helps.

Thanks, i will need to study your plan in and try to conceptually apply it, initailly i will need to install (45 degrees) of the 180 drgree radius you provided, or 1/4 of a 360 degree circle / as a right graduating elevation turn / without a switch, RE: flex track .

My problem is getting the photos from my camera to the computer.  (Yes, a camera.)

In my experience, typically there were two ways of getting digital pictures from a camera to a computer.  A USB cable is traditionally used to connect the two devices together.

1) Cameras usually come with software that will give you control over moving the pictures to the computer.

2) When you plug your camera into the computer via the USB cable, it will show up in your directory (Windows Explorer or This Computer) as an additional drive (like a flash drive).  You simply navigate to the folder where the pictures are stored and copy/paste them to a folder on your C: drive.

These days I mostly take pictures with my smart phone.  In that case I navigate to the pictures on the phone and choose "share" and the use my gmail to email the pictures to my self.  Then I go to gmail on the computer and copy the attachments to a folder on the computer where I can upload them to a photo host or other things.

Depending on your main line alignment running past or through your yard you can easily get more than a 36" radius into 18 inch wide shelves.

I agree. The 'around the walls' part of my layout uses 16" wide shelves attached to the wall; I was able to fit Kato's 31-1/8" radius (HO) curves on a 90-degree corner turn and could have fit in a bit larger. I would think 36"R would fit on 18" wide shelves quite nicely.

Question, where is the stated radius of a curve measured on a piece of track? Inside rail, center of track, outside rail?

[davidmurray]

Radius of a curved track has always been measure on the centre line.

Thus you need to keep it two inchs from a wall or table edge.  Track spacing is measured the same centre line to centre line.

Thanks to all for the assistance, I will follow the advice on proceeding with a scale drawing for the right turn radius that works best for my layout expansion . Bayway Terminal NJ
