Mike, I can guarantee that the tamper won't be used prior to 7 AM on Saturday morning!
Friday, I'm running the tamping crew. I'm going to plan for a 9 AM departure from Sheepscot, although this may change based on other railroad needs. We'll be working on "Davis Grade", which is just north of Brook Crossing.
Saturday, I'd like to leave Sheepscot before 8, so that we can clear the mainline for an 11 AM passenger trip.
