Two requests in one day about Y-turnouts means "something must be done". :)

Full adjustable split-deflection switches have been on my NOD list ("nice one day") for over 20 years. Without getting any closer. But in a couple of hours today I have come up with a stop-gap solution which works far better than I dared hope. Which means I am now kicking myself for not doing something like this much sooner. It does rely on the irregular half-diamonds, so wouldn't have been possible before Templot2.

I have added a new peg position at peg on split deflection:



This puts the peg on the TP switch toe position (CTRL-2) but at half the switch deflection angle. Which makes it easy to peg an irregular half-diamond onto a bit of plain track to create a switch front. The result is that I was able to create this with just a few clicks, and no timber shoving needed.

In practice in many track planning situations there would be no need to create a separate switch front, it could be pegged directly onto an existing approach track. Then rolling the rails to put the switch-front rail joints in the right place.

What's more, I can also add a new mouse action to make the peg angle infinitely adjustable for situations where something other than a 50-50 split is needed.

It's not a perfect solution, because being a half-diamond template some turnout functions are not available. For example you can't have a joggled switch -- a prototypical REA semi-curved switch with straight planing it isn't. It represents a typical curved switch of no specific prototype.

But as a quick alternative to a full construction using partial templates I think it will be very useful.

In the next program update. :)

regards,

Martin.

I have now taken this a bit further, and added an option to replace the K-crossing timbering with the timber spacings and rail joint positions from any switch you choose (or those for a custom switch). This works best if you match the K-crossing angle with the switch deflection angle. For example in this case I selected a GWR 10ft curved switch, and set the K-crossing angle to 1:37 to match:



This doesn't change any of the rail alignments, so it is still not a proper prototypical switch. But it looks better, with the switch tips correctly overlapping the timber centre, etc. (except for the NER of course). And if you choose a curved type switch from the list, it will be quite close.

Comparing the above with the previous one, you can see the improved timbering at the switch tips, and the rail joint positions.

This is now the alert message you see when accessing the switch settings dialog when there is a half-diamond in the control template:



regards,

Martin.

Thanks, but it's not trouble, I enjoy the coding and adding extra features to Templot. :)

It is writing the explanations and help notes which causes me trouble. Which is often a disincentive to making changes and adding new features.

For example in this case, how do I explain to a beginner just arrived from the Peco catalogue that to create a symmetrical Y-turnout it needs a split-deflection switch? That to do that the most convenient way in Templot is to use an irregular half-diamond template instead of a turnout template? That such a Y-turnout is entirely different from an ordinary turnout having contraflexure, which on the prototype is far more common as an apparent Y-turnout than a rare symmetrical turnout?

A full explanation needs several pages of notes and diagrams. But I will now remove the original symmetrical Y-turnout tutorial dating from 2001 and make a new video. It will take me far longer to do than the actual coding change. :(

regards,

Martin.

This has gone completely over my head, I have been asked to make a plan to copy a Peco small Radius Y turnout. I have just come up with a dogs breakfast, please can you point me into the right direction to make something which looks (and I guess works) far better

Thanks John

Hi John,

This is the closest I can get to the Peco template. File attached below (00-BF).

This is created using an irregular half-diamond, and therefore comprises 2 templates:




Overlaid on the Peco template:



K-crossing angle: 1:40

V-crossing angle: 1:3 curviform

regards,

Martin.

Thanks a million, every time I tried adjusting what I was doing it got worse

At the risk of being totally castigated. Is there really a problem if one's model is not truly prototypical.

Martin's superb program can be all things to all men and why not?

It's your own choice and Martin has made it possible.

On my GWR layout I use 3-bolt chairs. Because that is all that's available in 3mm/ft. Does it worry me? No :)

I think even in the ultra fine scales there are compromises, it is really down to the individual how detailed they want to go. If you are like Nigel in 3 mm scale and the only chairs available are 3 bolt, then that's all you can use

However if you model in one of the 4 mm gauges, then you not only have five (including ST flat bottom chairs) different types of standard chair within the C&L and Exactoscale but also a range of special chairs for both turnouts and crossings. I for one think the addition of the special chairs not only looks better but makes building them easier.

The best layouts seem to be those where the standards are maintained across all disciplines, so they each compliment each other.

Even with all the choice available in the 4 mm gauges and we are relatively speaking spoilt for choice, there will always be something that is not available, for instance, whilst 3 bolt LSWR chairs are available slide chairs to match are not. You pays your money and takes your choice.

Same for GWR slide chairs, and most of the special chairs are for 3/4 bolt chairs

For GWR slide chairs I use the outer part of the standard chair and slide plate of the slide chair as a compromise, likewise for some special chairs as well
