Thanks to everyone for a very enlightening discussion. Such strongly held views and passion. Great stuff! I followed the thread because after 10 years of live steam and battery power, I'm attempting to try track power on my 45mm Peco garden railway (with standard rail joiners). This has been prompted by the arrival of Thomas and friends, and my grandchildren finally showing a bit of interest. I couldn't bring myself to attempt to convert Thomas (his eyes seemed to be watching me), so I though I'd have a go through the track with the supplied analogue controller. Much to my surprise he ran quite smoothly over most of my railway - after my usual going over with a plastic scourer on the end of a stick, and soldering the primary electrical connection. He performed best on sections where I hadn't touched anything for many years (ie not breaking the electrical connection). I've now spent a day replacing some sections and generally levelling things up. I've put a secondary power feed about half-way round, but I don't think it was actually necessary. My initial go at track power is a success so far. Why didn't I try it before?
