RMweb Gold MarshLane Posted October 15, 2016 RMweb Gold Share Posted October 15, 2016 Morning all,I'm looking at a project to built a short section (probably 8-10 foot initially) of double track that has been electrified. Nothing complex to start with, just two straight lines that are slightly curved. The idea is to use a combination of single post, single arms located either side of the track, single post double arms located between the two tracks, and a gantry style spanning both lines.Has anyone attempted 7mm electrification before? If so any tips? The aim is to create a light rail system, something akin to the Tyne & Wear Metro back in the 1980s.I've come up with a test bed over the past few weeks, but the problem is what to use for the overhead wire, and how to keep it taught. I know I'm going to have to scratchbuild it all, but any thoughts/suggestions would be welcome ... I'll post some pics of what I've come up with over the past few weeks shortly.Seriously, any thoughts, suggestions, drawings, pictures would be very welcome from anyone!Rich Link to post Share on other sites More sharing options...
david.hill64 Posted October 15, 2016 Share Posted October 15, 2016 There is a magnificent 7mm layout based on Woodhead electrics. I cannot remember the name now. Have you tried the Gauge 0 guild website? There is a lot of good information there. Link to post Share on other sites More sharing options...
RMweb Gold MarshLane Posted October 15, 2016 Author RMweb Gold Share Posted October 15, 2016 Hi David, Oh I didn't know about that Woodhead layout, I'll have a trawl online and see if I can find that. I am a member of the Gauge O Guild and did have a look at the website (albeit only briefly) but couldn't see anything immediately, so I'll go back and have another look. Thanks for the input.

RMweb Gold Joseph_Pestell Posted October 15, 2016 RMweb Gold Share Posted October 15, 2016 See also Jamie 92207's thread on Lancaster Green Ayre - although that catenary is rather more complex than you are looking at. Since you are modelling Tyne & Wear Metro style light railway, you may find more inspiration (and suitable parts) via Tramway & Light Railway Society. Lots of 7mm tram modellers. Edit: That should be 92208. Link to post Share on other sites More sharing options...

What a superb layout, that's my reading for this afternoon sorted out.

Thanks Joseph, that's one I'd thought about but assumed it was more interest in the real thing, another one to look at! Cheers Richard Link to post Share on other sites More sharing options...
RMweb Gold MarshLane Posted October 15, 2016 Author RMweb Gold Share Posted October 15, 2016 Brian/David, Thanks for the heads up on the Woodhead-based layout, Netherthorpe Sidings - truly superb. I've posted a query on the thread about the OHL, so i'll wait and see what comes back. These were my first two early trials. My big query is what people are using for the actual contact wire in 7mm scale, and is it just being soldered to the carry arm? Obviously, this is a very amateurish first attempt, but I was trying to gauge the height of the stantions, along with where the arms needed to be soldered for the contact wire. This was my attempt at a single line mast, using plastic H girders, with brass rod soldered together. There still needs to be some form of contact arm to attach the OH wire. Apologies in advance, to those in the know, if my terminology for the various parts is wrong! Rich Link to post Share on other sites More sharing options...
RMweb Gold Joseph_Pestell Posted October 15, 2016 RMweb Gold Share Posted October 15, 2016 Different scale but you might like to take a look at Vecchio's thread (Donnersbachkogel???) as he also makes his own. Link to post Share on other sites More sharing options...
RMweb Premium DavidLong Posted October 15, 2016 RMweb Premium Share Posted October 15, 2016 Different scale but it may be worth having a look here: https://roundtreessidings.wordpress.com/ Features quite a lot about the OHLE on the Tyne and Wear Metro. In 4mm scale they use 0.5mm wire for the contact wire. David Link to post Share on other sites More sharing options...

David Thanks David, yes I've seen the Roundtree Sidings layout - superbly done, although never seen in the flesh so to speak, so thanks to the other David for the heads up - definitely going to have to put Doncaster on my to do list now!

RMweb Gold MarshLane Posted October 22, 2016 Author RMweb Gold Share Posted October 22, 2016 Does anyone know if there are any 7mm insulators for OHL equipment available? Either plastic or 3D printed? I've not come across any as yet, so may have to try and create one myself to be 3D printed - in which case, if anyone has any real life dimensions or drawings they would be willing to share, it would be much appreciated.

RMweb Gold MarshLane Posted October 24, 2016 Author RMweb Gold Share Posted October 24, 2016 In case anyone comes up with a similar query, I have found that Sommerfeld do some O gauge plastic insulators - two varieties in both brown and green - available from their UK distributor, Blackwells of Hawkwell.

RMweb Gold MarshLane Posted December 5, 2016 Author RMweb Gold Share Posted December 5, 2016 Anyone interested in OHL may be interested in this book that can be downloaded as a free PDF http://www.railwaysarchive.co.uk/OLE/ No connection other than as a downloader!

RMweb Gold Revolution Mike B Posted December 6, 2016 RMweb Gold Share Posted December 6, 2016 You may want to speak to Pete Besant at PRMRP - he built all of his OHLE on Calvercar Town himself. Mike Link to post Share on other sites More sharing options...
