Hi Dave,

It is called a "double junction". There is a video showing how to create it in Templot -- click the help > watch a video > Scruff Video curviform double junction menu item.

Ask again if it is not clear. :)

regards,

Martin.

Hi Martin, I released I already looked at this video and duplicated it on my templot

But what I was really asking , is if you look at the photo the arrangement of check rails etc, seems to suggest its not a diamond.

Is there a way to duplicate the prototype track work in templot

assuming I havent the wrong end of the stick

regards

Dave

Hi Dave,

It is an irregular diamond, as often found in double junctions. The shortening effect of the long camera lens is making it look sharper than it really is. I can't see anything unusual about it, and I don't know any reason why there would be for an ordinary double junction.

It can be created in Templot as in the video, and explained in this topic:

 http://85a.co.uk/forum/view_topic.php?id=2617&forum_id=22#p18013

Replicating the prototype exactly is certainly possible. It may require some of the more advanced adjustments in Templot, although this one looks fairly standard. It also requires of course that you have a full drawing of the prototype to work from.

regards,

Martin.

Im aware of the effect of the lens, I have created the crossing in Templot, and I can correct the check rails using Adjust check rail end etc

But while I can adjust a check rail end position, I cant adjust a check rail start position ? i.e. I select MS2 and I can only move the end flare , not the position of the start flare


thanks again

Dave

The check rail is in the normal position, it is the effect of the lens making it look odd. If you moved it towards the camera the first train over the crossing would be derailed.

Use MS1 not MS2 to move the start position, but you can't move it past the 'A' timber (carrying the nose of the crossing), and you shouldn't even move it that far. If you really wanted to do that you would need to add the entire check rail on a separate partial template, although it wouldn't match any known prototype. :shock:

regards,

Martin.

p.s. Dave, here is a bit more info, taken from:

 http://85a.co.uk/forum/view_topic.php?id=1465&forum_id=1

The functional length of a check rail (i.e. the middle bit between the flared ends) must at least cover the break in the opposite rail. So for a V-crossing that means from the knuckle bend in the wing rail to approximately the centre of the A timber under the nose:



In practice of course it would be very unusual to have such a short check rail. It would need a severe speed restriction and is only likely to be found in yards and sidings.

Note that for model gauges with overscale flangeway gaps, the knuckle is further from the nose and hence the minimum check rail will be longer to ensure proper running.

The check rail is much more important for traffic running in a facing direction, so the working length of a check rail is normally much longer than the extension length (see diagram).

Martin.

Thanks Martin, all understood, just trying to recreate the prototype , which seems to have short check rails on the crossing , that whole area had a 15 mile and hour speed limit typically
