Pan Am Railways originally operated under the name of Guilford Transportation Industries and leased the operation of it's approximately 450 miles of main line and it's extensive branch line service to the hands of Springfield Terminal Railway. They in turn operated under these three former railroad names, Boston and Maine (BM), Maine Central (MEC), and Springfield Terminal (ST).
