Lee,
Thanks for sharing (your video) with us!
This is exactly the type of operation I'm trying to emulate with my model railroad - rural secondary line in granger (i.e. farm) country. While I model the north-central area of the upper Midwest, the geography and industries of the M&D certainly look familiar.
Watching a crew go about their work on a local is fine inspiration towards my modeling, and also a great afternoon pick-me-up after being away from trackside (railfanning) for too long. It sure gets the modeling juices flowing again!
Great job! (and I've bookmarked that page to watch the video over when time permits - it's that good!)
