Chrissaf Posted January 18, 2020 Share Posted January 18, 2020 HiYou will need to isolate the track with insulated track joiners.Look up DC wye junctions Link to comment Share on other sites More sharing options...
LCDR Posted January 18, 2020 Share Posted January 18, 2020 Triangles and return loops in a two rail situation needs special switching to prevent short circuits. This occurs because at some point the positive rail meets the negative rail. What is needed is an isolating section between the points where the train can stand while the polarity is reversed. The isolating section has to be at least as long as your longest locomotive with isolating rail joiners in both rails at both ends. The isolating section is connected to the power supply by a double pole double throw switch with centre off, wired so that the polarity to the isolating section can be swapped while the locomotive stands in it. At the same time the controller direction will also have to be reversed. Link to comment Share on other sites More sharing options...
Chrissaf Posted January 18, 2020 Share Posted January 18, 2020 Jamie,As you have correctly identified a triangle (called a WYE in railway speak) generates a short circuit. In a DCC layout it is possible to use a fairly simple automated all electronic switching solution. However this is not possible in a DC Analogue layout..This previous thread discusses how to tackle a WYE in DC Analogue in some significant depth:.https://www.hornby.com/uk-en/forum/layout-advice-please/?p=1.TIP: As this is your very first post, just be aware that the 'Blue Button with the White Arrow' is not a 'Reply to this post' button.

Chrissaf Posted January 18, 2020 Share Posted January 18, 2020 Hi, I'm new to modelling so could do with some help.i have a loop with 2 sidings coming off which work fine Independently, however I want to connect the 2 so you can go in and out of both . I have done this with y points to create a triangle but this causes problems with a short circuit when I try to go between the 2.I'm running a dc circuit, is there an easy way to solve this ?hope you understand what I meanthanks Jamie Link to comment Share on other sites More sharing options...
walkingthedog Posted January 18, 2020 Share Posted January 18, 2020 In all my years of railway modelling I have never heard of the term "WYE". Have now. Link to comment Share on other sites More sharing options...
NWR-Gordon-4 Posted January 18, 2020 Share Posted January 18, 2020 I have never heard of it either, until I read this thread. GNR-Gordon-4 (HF) Link to comment Share on other sites More sharing options...

walkingthedog Posted January 18, 2020 Share Posted January 18, 2020 I'm not looking for proof Chris, just never heard of the term. Y points yes, WYE meaning a turning triangle no. Every day's a new day. Wiki not the best example to use. 😆 Is it an American term? Link to comment Share on other sites More sharing options...
NWR-Gordon-4 Posted January 18, 2020 Share Posted January 18, 2020 Thank you for the hyperlink Chris. I was not looking for proof either, as I believe everything I read here, but your Wikipedia hyperlink will still make a good read anyway, I am sure. 😉 😀 GNR-Gordon-4 (HF) Link to comment Share on other sites More sharing options...
Chrissaf Posted January 18, 2020 Share Posted January 18, 2020 Wiki just happened to come top of my Google search list. And after a further search, all the links I have found seem to point back to the Wiki entry..I know I didn't need to provide proof as WYE had already been mentioned by Jane in the previous post. I just provided the link for general information for anybody who might be interested..Is it an American term?.To be honest I don't really know, but the Wiki entry lists some American resource material at the bottom of the page.....so it could very well be..I've just always known it as a WYE from when I was researching the content for my 'Reverse Loop Tutorial' PDF that I sometimes post a link to in replies to poster's 'Reverse Loop' questions.

walkingthedog Posted January 18, 2020 Share Posted January 18, 2020 Chris I was going to say if it is from the USA, leave it there. 😆 Link to comment Share on other sites More sharing options...

96RAF Posted January 18, 2020 Share Posted January 18, 2020 I have always known a triangle track formation as a Wye junction, commonly used in the real world in lieu of a TT. - the old Dereham trackage had this arrangment. Where does the term come from - no idea - but it describes each corner of the triangle and makes perfect sense to me. Link to comment Share on other sites More sharing options...
walkingthedog Posted January 18, 2020 Share Posted January 18, 2020 I have heard of a Y junction not Wye. I wonder if LC has heard the term. Link to comment Share on other sites More sharing options...
96RAF Posted January 18, 2020 Share Posted January 18, 2020 Wye is just a phonetic version of Y. Link to comment Share on other sites More sharing options...

DBfan Posted January 19, 2020 Share Posted January 19, 2020 Is it an American term? Yes it is smae as ties for sleepers and turnouts for points Link to comment Share on other sites More sharing options...
walkingthedog Posted January 19, 2020 Share Posted January 19, 2020 In that case let it stay in the USA. Link to comment Share on other sites More sharing options...
