Mick Nicholson has kindly supplied an interesting collection of track detail pics. Many thanks Mick. :thumb:

Most of these can be seen at a much larger original size (and with captions) by viewing them in the Image Gallery at:

An excellent resource of useful stuff!
Regarding the picture of the double junction being relayed, Mick sent me a copy of this previously and, despite the caption, I am not convinced that these are C10 - they look much more like C8 to me. Any views?

Regards,

Howard.

Hi Howard,

16 "T" timbers in the picture between the stock rail joint and the wing rail joint.

At the default spacing Templot makes that a C9.5

But of course it depends on the fill timber spacing setting. On balance I think these turnouts could be in the range C9 to C10, but there are too many timbers to be C8.

Mick says C10, and 10 is the "natural" angle for a C switch, so I'm inclined to take Mick's word for it. Unless anyone can spot evidence to the contrary?

It wouldn't be longer than 10, because that would normally require the check rails to span 6 timbers and the wing rails to reach to the C timber.

regards,

Martin.

Hi Martin,

I used the counting timbers approach also but thought that 16 corresponded to a C8 - happy to concede the "point". Mick mentioned that the chap who captioned to original has a PW background so he might know a thing or two, but I was expecting a C10 to have 19 timbers in that space, and the check rail made me think it might be a tighter radius than a C10. But maybe the learning is that the protoype demonstrated a lot of variation - hence the pics are so useful.

Best Regards,

Howard.

Hi Howard,

I've now looked at this more closely, and I'm tending towards C8.5 or C9.

exact scale, generic crossings, CLM angles:

To get 16 timbers in a C8 requires them to be at 26" spacing all through, which looks too tight to me (template 4 above).

But a C10 is clearly too long and requires more than 16 timbers. So my bet is now on C8.5 (template 2 above).

Interesting discussion. :)

regards,

Martin.
