General Service Characteristics Length of Haul Internal carriers average haul 482 miles Great Lakes carriers average 508 miles Coastal average 1652 miles Load Size Barges normally transport 1000 – 1500 tons (max capacity 3000 tons) Equivalent to 16 railcars or 60 trucks Great Lakes carriers average 20,000 tons

General Service Characteristics Speed of Service Transit time longest of the 4 modes that move non- liquids Speeds average between 5 – 10 miles per hour (upstream vs. downstream) Service Disruption Ice Hurricanes
7
Types of Vehicles Tanker Largest ship in domestic water industry 18,000 – 50,000 tons Barge Most commonly used vessel by internal waterway carriers Powerless (towed by a tugboat) 1500 – 3000 tons
