Dual Gauge

[Dave Cooper]

Hmm, - much food for thought here...

Looks like modifying R-T-R will be problematical !

'Self-built' track looks a possible, especially if I could find a proven template and suitable parts for the pointwork. The moving blade and frog idea is really fascinating - I'm just thinking about the electrical side of that though...

Many thanks for all the contributions so far. I'm sure there's a solution here somewhere.

There should not be any electrical problems , it should operate as a normal point . In actual fact on my suggestion and Brian's picture you only actually need the straight blade of the point to operate . The curved section of the point could be made continuous for 009 ,with the straight blade open and only closed when you want 00 running .

Don Borehams wonderful book on Narrow Gauge Railway Modelling gives good diagrams of mixed gauge points and suggestions as to how to build them.  Probably not expensive on ebay.

Not strictly the same: The Ravenglass and Eskdale once had the Standard gauge straddling the narrow gauge. So 4 parallel rails.
Never seen a photo of now the two met and separated, there must have been crossings of some sort.

I think on the Ravenglass dual gauge the normal rail profile for the two gauges was so different that the crossing sections actually involved bits of rail being lifted in and out. There's one or two places with 2ft and 7 1/4" dual gauge that also have this. Similarly Tillig H0/H0f track is actually 4 rail (unlike the H0/H0e and H0/H0m versions) with the 6.5mm gauge using a smaller rail profile.

Lots of good points (ha ha!) from lots of contributors.

Regarding four-rail (sorry, I did mean 'rail', not 'track'), I would not say it complicates things because it eliminates the need for moving or interrupted rails, becoming simply equivalent to gauntlet track.

Anyway, it's the approach I'm taking.  My current challenge is the frogs.

Blair - any ideas how I would get in touch with the seller (I'm not on the "NGRM") ?

I predict Peco are working in secret on dual gauge track options.

There's always the eternal optimist!! :)

I'm afraid the only way is to joining it (us!), Dave. It's well worth it, there are lots of 009 modellers on there and lots of NG info.
