Movie Mondays #5

Of all they youtube videos I've watched over the years, this four-part series on operating model railroads by Chris Lyon and Mike Hamer has done the best job of introducing the concepts of operations to those of us who know little about how a model railroad should operate.  I found their videos to be invaluable when designing my own little layout. Here's part one, but be sure to check out the other videos in this series as well.
