Ian, it is single track, it was never double track. The main sections are set up to be double tracked, but never where. It was almost double tracked, but when the CV and GT did not bring together the plan for the SNE, the BM kept ot single track. Basically, the BM and CV used that line to Dole Junction then across the river again (the famous bridge that the pier subsided and leaned over) to East Northfield. The CV line from East Northfield to Brattleboro was the Southbound Main and the BM line in the New Hampshire side was the Northbound Main. This was a odd way to double track the line.
