 From Princetown, where the terminal was intended for general merchandise servicing the small community there, the line ran west, passing between the Foggintor Quarry (to the north) and Swelltor Quarries (to the south, on the promontory formed by King's Tor); it swept round the north of King's Tor and to the west of Ingra Tor, now heading general south past Peekhill and across the western flank of Yennadon Down.South of Dousland there was a sharp turn to head north again, to maintain the contour, passing west to Yelverton where the line passed through the centre of the common.Close to the Roborough road, the line descended southwards curving past Clearbrook, and now with multiple twists the line descended to the west of the Tavistock Road through wooded terrain, before turning west through Leigham Tunnel.
