This was a new one on me. A Loram Railvac is eastbound on the CSX Peninsula Sub on 7/28/12. From Loram's web site:
RAILVAC™ is a unique excavation machine that conveys material through vacuum and airflow. The machine is rail mounted and designed to travel at track speeds while towing up to four fully loaded ballast cars. The combination of a powerful digging arm with twin engines and vacuum pumps makes it capable of excavating compacted ballast, clay, mud, water, sand, and soil. The digging arm can work at distances up to 15 feet from track centerline.
Material is extracted through the suction hose and deposited in the main hopper. The finer dust then runs through a filtration system, removing the dust from the air stream. The filter elements are cleaned automatically by the air counterflow during the routine unloading of the system. A rear swing conveyor, or optional side dumping doors unload material.
