Why build a model railway? I'm sure many have asked modellers this over the years, of course one reason is that it allows you to explore many different skills including wood working, painting, planning and basic electrics. The latter can involve use of the soldering iron which is something i used a fair bit in the past when i did the odd bit of electronics but not for the last 20 years or so.
Until now, the power clips i was using were just a total fail so i decided to solder the wires onto a piece of track. Not the easiest task in the world trying to hold a soldering iron (and not a tiny one at that), solder, a wire and a piece of track with just 2 hands available! We got there in the end though, i managed to only melt a couple of sleepers! It was all worth it as the train runs great.
