Some actually depend on gravity to help move the cars around. There is usually at least one yard in most communities of any size. In major metropolian areas multiple yards can be found, especially if more than one railroad serves, or served, a city. If you can find a good vantage point, the operations in a railroad yard are fascinating. Remember, as a railfan safety is the first thought in your mind.
Railyards are private property and no place to wander around in.
The danger is extreme down on the tracks. Besides the best place to watch a rail yard is on some high vantage point where you can see all of the action and appreciate the expanse of such installations. I will put as many yards as I have the opportunity to photograph on these pages. Follow the links below to check them out. This section is under construction.
