Curve Template

[affinityone]

Have used a number of templates from DLS but really need object comprising a set of concentric circles from say 50 metre to 150m radius for tight curves especially in industrial areas and visible only in surveyor.
Any one willing to develop one for me would have my eternal gratitude.

I second your motion, Geoff, and putting it on the DLS or somewhere else for download would be a big help to everyone. I think one in 10 or 15 or so meter intervals would be ideal.

There are two that are great, by maddog1169:

Curve Radius 100-600m 90 degree KUID2:142427:30000:2
Curve Radius 750-1500m 30 degree KUID2:142427:30001:2

They can have the lines: height range -500,500 placed in the config file, then they can be used on a DEM also, by moving them up and down.

You hold the mouse still and use the R click (or KB command) and place 6 of them exactly at the same location, then spread them out by rotating them into a full circle. I have even re-skinned these into black color (as they are bright red) on my own PC to make them easier to see and use.

I use FT 75m Radius Track as a guide for smaller radius curves ... there are other sizes also.

CascadeRail, Thanks for 2 ideas. Thought I had covered everything, guess I continue to learn.

Geoff --

50m is extremely tight. I suggest nothing less than 200.

My favourite is "90d_100-400m Template". It's very easy to use.

The Horseshoe Curve is the equivelent of a minimum modern mainline curve, @ 250m radius ... I have used a 50m & 75m radius on the NG Wopsononock RR backwoods brachline.

Most of my turnout double crossovers are 125' to 200' in length, points to points.

Thanks for all your suggestions. Agree 50m is tight but I do have a few at this radius, mainly short yards/spurs with "no loco" limitations. Have used most of methods suggested but find laying an smooth short radius more difficult than 200m mainline curve and was looking for template to help out.

Just the loco for your 50m curves

Geoff --

If you really do insist on 50m, I have just the locomotive for you. See my post #2624 here:

I did this a couple of years ago to illustrate the use of templates in making switches:

Yes, 50 metres is tight - but not for trams! I use 25 metre radius for some of those.

Ray

Second thought - I should have said that this is what I use for continental four-wheel trams with two or three trailers in tow, to avoid any 'clashing' between the separate units. It also works well for modern articulated trams. For traditional UK trams, 13 metres would I believe be prototypical.

One way of laying tight curves is to use the baseboard grid and lay appropriate markers - could be the built-in 'push pins' although I use my own (Surveyor only but they can of course be deleted after track is laid) and use them for laying the track. A track with very short spline section length is necessary.

Back when railroads in the US actually delivered one or two cars to industries in industrial districts in cities rather than restrict themselves to unit trains and container yards, 50 meter curves and turnouts down to # 5 1/2 were used when they couldn't be avoided. EMD NW and SW, and Alco switchers were and are capable of negotiating curves as tight as 30 degrees, which is 58.2 meters, according to my information. This was necessary when negotiating street trackage, which was common everywhere, or a complex industry, and possible when the commonest freight cars were only 40 ft. long rather than the much stiffer 90 foot equipment common today.
