Ok, i'm trying to catch some of csx action in mansfield, ma and be one of those cool guys who take photos of trains. So i found this site http://www.bullsheet.com/news/freights.html so ive tried following the schedule but i havent seen squat. Are there anyh other sites that have schedulaes? How good is this bull sheet? Is it updated often? Whats the scoop with the bull sheet?
