Greg,
It sounded like this was going to be a recurring event. Especially if it proves popular enough. (And how could it not?)
It looks like there will be a regular train Thurs-Sun. at 10:00 a.m. during this time frame as well. The trains would have to meet somewhere. Tacoma? Would be worth a good runby as well.
For me at least, I just came from the D&S in August, and it would be a stretch to go back so soon. Seeing the 473 in yellow before it gets painted would be a good motivator, as I dearly wanted to see it when they first did the paint job.
