GWR Y-turnouts and Catch points

Hello, I am brand new to the world of Templot and coming back to the hobby itself after a long hiatus.
I'm in the middle of planning a 00 gauge GWR BLT of semi realistic design (Some Rule 1 aspects have applied) and started with a basic design using AnyRail.
A friend, who is currently building his own layout and point-work from scratch, suggested the use of Templot to perhaps increase the realistic representation of my layout. By making my own pointwork using existing data on GWR specifications.
I have watched several hours of tutorials and read a lot of the documentation and I am fascinated by the program and the community. However, I am stuck on 2 aspects:
- Wye turnouts (I have one at the beginning edge of my layout and 1 in the good yard)
- Catch points (I have one to protect the main from the goods yard and one from a parcels bay)
I was wondering if anyone can provide some information on how to achieve this best, be it an external book source I should enquire into or a forum post I have missed, or a tutorial on the subject and their creation using templot.

Thanks in advance and I hope to be using Templot for a long time to come!

Yes, but Google is 7 years out of date. :(

Ignore all that, and see the link here, as in my post above:

https://85a.uk/templot/club/index.php?threads/changes-in-templot-version-227.180/post-1501

This illustrates a major problem -- Templot is constantly changing. After 22 years of Templot online, vast swathes of Search results are now out of date. What to do about it without losing stuff which isn't out of date is not at all clear to me -- what does other software do?

cheers,

Martin.

Thank you @Martin Wynne :) I was slightly confused when I saw 'Archive' but nonetheless both articles will help immensely! Does this include Catch points? At a quick glance I cannot see mention of it. Perhaps a simple play with templot will bare some fruit.

Perhaps simply setting thread of +5 years a tag of "Legacy" or something along those lines. Other than sifting through each to find which is newer and more relevant can you truly find what is old or not.

@LittleWestern

Hi,

I have now seen your trackplan on RMweb:

not_y_turnout.png


and as I suspected when I read your first post above, that is NOT a Y-turnout.

Y-turnouts are not used in running lines because splitting the switch deflection imposes a speed restriction on both routes. Except perhaps in very long high-speed double junctions -- but that is not one of those.

That is an ordinary right-hand turnout which just happens to have been laid into a curved line running to the left. Such a situation, called "contraflexure" or "negative curving" is extremely common on the prototype. But because as far as I know such turnouts have never been supplied by the model trade, modellers are blind to them and keep asking for Y-turnouts instead. Y-turnouts are quite rare on the prototype and always restricted to yards and other low-speed areas, they are not used in passenger running lines.

Contraflexure is extremely easy to do in Templot -- start with the ruling curve and insert a turnout into it. An ordinary handed turnout. Swap the hand from one side to the other as needed:

not_y_turnout2.png


not_y_turnout1.png


Above is a constant curve running into the platform, with three turnouts inserted into it, two right-hand and one left-hand. There are no Y-turnouts.

This prototypical way of track planning is of course entirely different from using a program such as AnyRail, and joining together fixed commercial track pieces.

It makes me sad that after more than 40 years of Templot I still have to keep explaining this over and over again. Contraflexure is everywhere on the prototype (but nowhere in the Peco catalogue). Here for example:

20100725%2066951.JPG

linked from https://www.cardiffandavonside.org.uk

The turnout alongside the locomotive is an ordinary left-hand turnout forming part of a crossover in curved double-track. It's not a Y-turnout.

cheers,

Martin.

@Martin Wynne

Thank you for the great in-depth analysis!
It makes a lot more sense to me now after doing some more reading and research and is exactly the reason I joined and started to use Templot in the first place. I wanted to shy away from using 'SetTrack' as it is because it didn't feel real and now Templot has given me that aspect. It wasn't until Templot and spending more time researching a realistic layout rather than a, god forbid me for saying it, "Train Set" so that is the original purpose of the 'Y' not so 'Y' turnout originally.

I have, since that post on RMWeb changed the layout quite dramatically, since it looks "functional" but much less, for lack of a better word, "proto-typical" than I would like. Realism is my goal for this project and all future extensions of the branch line I intend to create.
I may have a relatively small space now 2400mmx600mm(scenic) But I can still create something I like.

I plan to make a post today actually to document my journey using Templot and show progress at each stage.

The forum posts here have already taught me so much and given me even more to consider moving forward, for that I am grateful.

Cheers,

Another curved double-track crossover (Swanage):

The far turnout is an ordinary right-hand turnout. It is not a Y-turnout.

(It is worth clicking the image, and then the image again, for the hi-res original.)

Martin.
