Soldering Techniques?

[RobertInOntario]

The problem with soldering at the rail joints is that it leaves no room for track expansion with variations in room temperature which can, in extreme cases, lead to track buckling.
Here's a video showing you how to solder droppers for track feeds. <!-- m --><a class="postlink" href="http://www.youtube.com/watch?v=b1YkdrYlGbM">http://www.youtube.com/watch?v=b1YkdrYlGbM</a><!-- m -->

Thanks -- I'll check out that video.

I was going to ask if anyone could post some pics of well-soldered track but maybe this video will do that.
