Could do worse than copy what Triang did, a selection of mk 1 coaches and typical 1950s motive power.

Hornby can just use the artwork and adapt it. Ample room to stick modern mechanisms in the engine.

I have the Brit and Castle, excellent models. Can be done, but needs fine scale wheels. Otherwise don't bother.

I don't think Peco are daft; they've experience of this sort of thing and will have factored things in accordingly. 009 for example.

Whack some track down on a sheet of MDF and there's your layout. I'm impressed with the Corgi TT models and reckon something like those would sell for their own sake.

Sensible to produce stuff which enables people to get a moderate project off the ground fairly quickly. But I suspect the manufacturers will also want to throw in some glamour models fairly quickly; some people are more interested in simply running high quality attractive locos rather developing layouts as such.

The 1950s must surely be an attractive era to aim for. BR stock covering much of the country, mixed steam and diesel, etc

ah, missed that

Steve Flint in RM has an interesting article on TT-120 which includes a diorama of what it might look like; as well as the Peco stuff it includes other items which seem to been borrowed from other scales. I found it not that obvious which scale; the only obvious one to me was the N Scamell by the goods shed. All the other stuff seemed to fit in pretty well. I'm guessing that the station fencing is Ratio N. The double track road overbridge is probably a single track 4mm Peco product. The station lamps are probably N. All in all an interesting mix of scales. Nigel edit: also includes a Collett 0-4-2 and autocoach. Is it N, 3mm, or mockup of TT-120 version. Dunno.

Think you're underestimating how easy it is for a manufacturer to put together a chassis these days. it's getting the body right where the effort is.

I was talking about ease of building layouts; stock is something else. I suspect it would take at least a year for most people to build the basics of a modest sized layout in any scale. As to availabilty of stock, don't assume that Heljan are the only show in town.

If you read this month's RM you will find plans for two very buildable TT layouts. Not difficult at all.

The Bilteezi range of card kits for 3mm has always seemed to be under scale to me and should be about right. They can be made into attractive models, witness Mike Corp's attractive layouts.

Diifference with 00 is pretty obvious; much smaller. Maybe with N is not so obvious until you look at what Corgi have done with their static TT models; they have a fineness and presence which has eluded even the best N models, and show there is a clear slot between N and 3mm to be filled. My view is that to fill it manufacturers will need to aim for the highest standards, even if prices are high. Between TT and 3mm it's more difficult; currently it's between off the shelf, and a very wide range of kits and components which support those who build their own. Though a 3mm modeller, I'd be surprised if I didn't try a, probably modest, TT project, just out of interest; I like this sort of scale and done properly think it deserves to succeed. Nigel

Link seems fine for me. By the way, these are the MOROP/NEM standards. it'll be interesting to see what actually turns up; to me the pointwork looks finer than those standards.

This appeared on the other thread; https://ips-cic-filestore-eu.s3.amazonaws.com/y320084/monthly_2022_06/nem110_en_2009_20111116_pdf.b4a95567fdbf391a46d62e47304eb5d3?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIAW7MTEBD3WCZ2IG4H/20220616/eu-west-3/s3/aws4_request&X-Amz-Date=20220616T180302Z&X-Amz-Expires=1200&X-Amz-SignedHeaders=host&response-content-disposition=attachment; filename*=UTF-8''nem110_en_2009_20111116.pdf&response-content-type=application/pdf;charset=UTF-8&X-Amz-Signature=cf752ea22da3e2ce2667b03e597b94bb4077cf53efc04ff4cdb13366e1643c48 If this is whet Peco is using, then it's essentially the 3mm Society Intermediate standard for 12mm.

Triang dropped TT because traders proved very reluctant to stock two scales; it was a different world back then. Today the online marketplace means that customers can buy direct.

In the current economic climate companies need sales and new ground breaking products are more likely to sell than yet another rehash. And it should be noted that Peco have priced their TT products at quite a competitive level.

I'm a great admirer of the Corgi TT engines which nicely capture the presence of the prototype. They have cast metal bodies. As I understand it, this approach is potentially cheaper while adding useful weight. Wonder if this might be used to produce new models while keeping costs down.

Lot of assumptions there, Wim. I'd rather take things at face value and see what emerges, and at face value they are serious about British TT, otherwise they'd have done things differently .

I don't think we're talking about Peco + 1 other. I suspect quite a few have been involved and maybe for quite some time. Hornby, Dapol, not sure Bachmann would be interested. Metcalfe and others on the scenics.

Nothing wrong with wheels much closer to scale. I hope this TT aims towards the top end of the market. No compromise.

what's wrong with UK outline 2.5mm/ft? Corgi did some very nice static models in that scale.

It's TT pure and simple, model railways at 1:120. 14.2mm is only correct if you model to 3mm/ft, a different scale. Peco obviously isn't in this alone; others will be working on stock.

In spite of being a 3mm modeller, I think this is a great development. An attractive scale and throwing out the usual British compromises. Could tempt modellers in other scales looking for a new project to try out. I'm sure the rolling stock will appear; I've been impressed with what Corgi achieved in this scale. I see this very much aimed at the British market; it's very much a scale for people to dabble in. Nigel
