well, recently i discovered somthing incredible. my health teacher, Mr. Nelson (i'm a freshman in high school) had a grandfather who worked for the B&M durring the steam era. he opperated trains between boston and portland, and back in the 90s, he assisted with the steamtown move to pennsylvania (mabey because the P4 4-6-2 constitution was his engine? still trying to confirm that). my teacher has numerous pics, so i'll try and get more info.
