Bucksgahuda and Western Railroad

I am planning on going down to St. Marys this weekend for the open house and was wondering what to expect. Will both steam locomotives be running? If so how? Will they only run one at a time - one in the morning and one in the afternoon, or will they be running the same time, or double headed?!?!?!? When do the trains start running? I am trying to plan my son's nap so he sleeps for most of the drive (he does not like 3 hour trips - actually either does my wife but anyway...). What is the trip like this year? The last time I was there we went out the new extension then backed back and then did the loop, is that still the same?
I was just watching my videos from 2004 and the scene with the 0-4-0 coming up the big hill is just awesome. That little engine sounds like a 4-8-4 and then it slips for a second and picks right back up and gets even louder!!! - oh man I can't wait to get down there!!!!!
