While everyone else there was hanging out around the depot, I decided to hike down to where they were servicing 4501. They had the smokebox door open and had a rake raking out a boatload of soot that had built up inside it. I've got a photo of them pulling out that soot. I'm planning on putting up a few photos I took of them servicing 4501 sometime. Worth noting was that I was on the 10am excursion on Sunday. I was in the Florida East Coast coach. The ride was relatively smooth, though there were a few times where the slack wasn't pulled out smoothly. Reminded me of The Polar Express when it starts moving.
