In this photo you are looking at one of the switchback tracks that's used when two engines are passing. We were heading up at this point. An engine and car coming down from the top would pull over and let us pass, and then the track would be moved back to the left. You can clearly see the teeth in this picture, and in the distance a water tank for the one steam engine that makes the trip once a day. On this narrow gauge track the engine and car just 'zips' along up the mountain. Of course, we're all cogs in the big picture of the world at one time or another. When we function as: a member of an organization who performs necessary but usually minor or routine functions, we're cogs.
The railway of life just keeps chuggin' along.
Clickety clack, clickety clack...
