Lawrence, Mass. - CPF-FR
1/31/2016 - Two Pan Am engines are waiting to go east with a 6 car freight train. They are being held at the interlocking known as CPF-FR waiting for a westward passenger train. Even though this is a double track line it is being operated as a single track line because the westward track on the Merrimack River Bridge in Haverhill is out of service because of a major bridge repair project.
