• Caption: Loram Railvac #LRV-2 is parked at Readville on the lead to the former New Haven shops. The Railvac is an excavating machine that vacuums up ballast, dirt and the like. The suction hose on the front can reach both between ties and up to 15 feet away from the track's centerline. Judging from the amount of Amtrak equipment accompanying it, it was in the area working on the Northeast Corridor. (March 7, 2010)
