Ben C Posted May 18, 2020 Share Posted May 18, 2020 Hi, I've recently been laying track and wiring on my OO gauge 8x8' roundy roundy. I've been soldering droppers to each length of track and each point using the Gaugemaster 7/0.2 wire I picked up from my local shop a while back after being told it was the right stuff for the job. Been doing some searching tonight with a view to ordering my bus wire and have seen lots of places mention 16/0.2 as a recommended minimum for droppers. Have I gone too small and is it worth replacing before I do the whole lot. Have only done about half of my mainline loops so far. Would be a pain to replace but not impossible.

RMweb Gold Dagworth Posted May 18, 2020 RMweb Gold Share Posted May 18, 2020 7/0.2 is fine for the short lengths that your droppers should be. In most instances they will be paralleled through multiple connections from the track to the bus anyway Andi 5 1 Link to post Share on other sites More sharing options...
Crosland Posted May 19, 2020 Share Posted May 19, 2020 They will be fine, so long as they are not excessively long. If the bus wires follow the track layout then I would not lose sleep over it. There was a rather comical "readers letter" to, I think, MREMag, some years ago, that claimed thin droppers would set your layout on fire. 1 Link to post Share on other sites More sharing options...

I remember that, it was hilarious! Andi Link to post Share on other sites More sharing options...
Ben C Posted May 19, 2020 Author Share Posted May 19, 2020 Thanks for the replies. I'll carry on as I am for now then. The bus wires will indeed follow the track layout so should be able to keep droppers to 6-8" or so. There shouldn't be more than one loco per track section at any time either.
