Tom-358478 Posted June 9, 2023 Share Posted June 9, 2023 Is there a website or resource where I can download a comprehensive guide for Hornby TT track dimensions? I'm currently undertaking a new project and I've been struggling to find the necessary information regarding sizes, radius, and other specifications.I'm hoping to find a guide similar to this one I came across for Kato Unitrack: https://www.unitrack-kato.com/Your assistance in this matter would be greatly appreciated. - TS Link to comment Share on other sites More sharing options...
P-Henny Posted June 9, 2023 Share Posted June 9, 2023 This is a recurring question. Previous forum guidance has been to download the free evaluation versions of either "Anyrail" or "SCARM" track planning software, that both have Hornby TT120 libraries.

Fishmanoz Posted June 9, 2023 Share Posted June 9, 2023 With these, they have limitations in the number of track pieces you can use. You can make layouts beyond these limitations by designing your layout in sections.If you are intending to use flexi track, you can also load the Tillig library as it contains such track.

D9020 Nimbus Posted June 10, 2023 Share Posted June 10, 2023 The website and catalogue are misleading; the uncoupling ramp must be fitted to a Hornby 166mm straight — it is not a track in itself. Link to comment Share on other sites More sharing options...
Moccasin Posted June 10, 2023 Share Posted June 10, 2023 They’ve updated the website now to just show the uncoupling ramp components. Link to comment Share on other sites More sharing options...
Rallymatt Posted June 10, 2023 Share Posted June 10, 2023 I think people were willingly mislead 🤣 the uncoupler was priced much less than a plain section of track so it was obviously not going to include the track….but it is clearer now on the website.

Moccasin Posted June 10, 2023 Share Posted June 10, 2023 Yes logic would strongly indicate that it is just the ramp, but…. Link to comment Share on other sites More sharing options...
Fishmanoz Posted June 12, 2023 Share Posted June 12, 2023 @Dwayne,Another correction on your listing - extended half straight length is 92.2mm, not 9.2cm as shown for the item in the Shop.This is symptomatic of a lack of attention to detail when specifying dimensions in the shop and elsewhere on the website. There are many mistakes in the track and other dimensions quoted. Examples include:full straight - 16.5cmquarter straight - 4cmDon't get me started on using cm not mm.

Rallymatt Posted June 12, 2023 Share Posted June 12, 2023 Cms? If only that was all….. we still have an anarchist mob that insists on using a system based to the size of various body parts of various Roman Emperors, A system we parked up 53 years ago!!!

Fishmanoz Posted June 12, 2023 Share Posted June 12, 2023 I am certainly not wedded to emperors/empresses but, as well as being able to think and operate all manner of measurements in the SI, I can still understand Roman body parts. If only I had turned my attention to languages instead of measurements. Link to comment Share on other sites More sharing options...
Dwayne-358518 Posted June 13, 2023 Share Posted June 13, 2023 @D9020 NimbusI know but to use it in XtrkCAD it needs the track too. Link to comment Share on other sites More sharing options...

This is a issue I run into with all mfg. web/catalog data vs actual, went creating track libraries for XtrkCAD. All I can do is use what I find and adjust dims, if/when I receive better data from folks. Link to comment Share on other sites More sharing options...
Fishmanoz Posted June 13, 2023 Share Posted June 13, 2023 Dwayne, I’m repeating what the Anyrail man has and I know he waited until he had correct data from Hornby before putting it in the library. Link to comment Share on other sites More sharing options...
Tom-358478 Posted June 25, 2023 Author Share Posted June 25, 2023 Seriously, Hornby? It's beyond frustrating that they expect us to do the detective work to find basic product information! We deserve better from a company that wants our money.How can they expect us to use TT tracks when they can't even bother to give us the necessary details? It's a complete letdown and a disservice to their customers.Sorry for the rant, but I had to get it out.. and let's hope Hornby gets their act together (soon).- TS Link to comment Share on other sites More sharing options...
Rallymatt Posted June 25, 2023 Share Posted June 25, 2023 All the dimensions and angles are in the print and online TT:120 catalogue and have been from shortly after the range announcement. It’s never been hard to find 😁 Link to comment Share on other sites More sharing options...
Fishmanoz Posted June 26, 2023 Share Posted June 26, 2023 Not just the catalogue, click on any track piece in the shop and all is revealed too. Or click on a track pack and the whole of the layout is revealed incl what the packs add. Yes, a geometry diagram like for OO would add a little, but not hard to find all the info you need right now remembering it’s simplified v OO as well. And just to add - too simple you say, what about curved or Y points or double slips? Do you realise you can drop in Tillig track for those, geometry is the same.

TheGreenGuit Posted June 26, 2023 Share Posted June 26, 2023 I sympathise Tom. I'm a complete beginner and the relevance of the various radii, relation to points, etc. were not immediately obvious at the outset. For example, the R6 curve brings the point curve back to parallel. That information is there but not something I would have spotted or even thought about. Track centres are 43mm apart, again easy to deduce by subtracting the radii but not obvious with no previous experience. Everything is written down somewhere but poorly collated and the forum search engine is pretty hopeless. I agree it would be helpful to have a comprehensive online description of the track functions or perhaps an article in the magazine and, not least, a track plan publication.One thing I have found invaluable is keeping a notebook as I keep forgetting or losing information sources. The pages I've devoted to accounts are a bit sobering, however. Link to comment Share on other sites More sharing options...
Rallymatt Posted June 26, 2023 Share Posted June 26, 2023 The hobby has always been quite ‘technical’ it relies on the participants learning things like geometry, electronics, carpentry and many other skills. I think the reason why the hobby has been so long lived is because it’s so involving. I was lucky being educated by the state in the 70’s when stuff like this was considered important (plus I wanted to run my trains so had the basic grasp of most things by age of 10) I would never want to put off newcomers to the hobby but these things are well worth learning, stuff like apps and playbox games are no substitute for the real thing. 😁 Link to comment Share on other sites More sharing options...
ateshci Posted June 27, 2023 Share Posted June 27, 2023 Model Railroading never was a hobby where everything you need comes ready-made. The items offered by the manufacturers are a basis where to build on, and in order to put your ideas into reality you have to gather all information you can get about them, but don't expect to have everything been digested for you. For me the hobby retains its fascination by urging you to use your wits and fantasy. Link to comment Share on other sites More sharing options...
Moccasin Posted June 27, 2023 Share Posted June 27, 2023 To an extent that’s all true, but of course you can get started in the hobby with a simple train set and take it as far as you want. HM 7000 etc has the potential to take some of the mystique out of the hobby. There is a danger of scaring new entrants off the hobby if they feel that they have to get deeply involved in electronics or wield a soldering iron. Not doing so might limit the boundaries somewhat but does not preclude enjoyment. I'm not suggesting that this thread is scaring others off, but I think there are some in the hobby who can be a bit dismissive of those who just want to set up a starter oval on a trackmat & are happy doing so.
