The message from "Steve W" contains these words:

S'right! Could be fun to model in 4mm...

Even more fun in 2mm!

It doesn't explain the points in the first picture.

The message from " snipped-for-privacy@hotmail.com" contains these words:

True. But I was answering the original point about standard/narrow gauge crossings. The n.g. points in the first picture are examples of

*basic* engineering - no refinements, nothing fancy - the point lever controls a moveable frog(can't call it a crossing) and also (so it appears) the stock rails. Perhaps it's a development of the stub points used in the quarries.

A couple more photos from Porth Penrhyn

the cross-over, I thought I had a photo of it closed to the 2ft as well but must be imagining things or remembering another book that I haven't got

and a fot of the stub pointwork, showing the moveable frog The only thing it doesn't show fully is the short section of track that moves to align, maybe looking at this next photo, which shows two sets of points in different positions.

Also in the foreground of the photo, the stub part of another set of points can be seen along with the marks in the ground from where the rails lay when the road is set to diverge, will help MBQ get his head round it :)

Somewhat like the complex manually-flipped switches on the Mt. Washington Cog Railway, New Hampshire.

- items 12 and 23.

Looks like the NG rails pivot so as to lie between and parallel to the SG rails.

ISTR back in the late 1960s, Mike Sharman had a piece of broad&standard mixed gauge track where the standard gauge was changing sides from one common rail to the other, with a narrow gauge track crossing through the middle of this at right angles...

This can not readily be depicted in ASCII, but whatever you're contemplating has to be easier to build than that.

I think constructing 4-rail Underground pointwork from scratch in N gauge in the dark might be easier than trying to represent that in ASCII art...

Sorry Trev, my internet connection died on me last night and has only just returned. Meant to say, thanks very much, very interesting trackwork.

Ok, these make everything easy to see! Thankyou for taking the time to scan them and put them up, much appreciated.

Not quite 00/009, but if you want to see mixed gauge track, then try and find Mike Sharman's standard/broad gauge layout. Fabulous trackwork, and some weird looking locos as well! Cheers, Mick
