While propane transports currently are loaded one at a time at the Rockville Propane Terminal in Rockville MN, that’s about to change. A major expansion is underway that includes upgrading the loading rack to load two transports simultaneously. In addition, eight more propane storage tanks are being installed. When the expansion is complete, Rockville Propane Terminal will be one of the largest rail propane transfer facilities in the United States.
