Aquatrain
The Aquatrain is an unpowered unmanned sea-going rail barge operated by Canadian National Railway between Prince Rupert, British Columbia, Canada and the Alaska Railroad in Whittier, Alaska, United States. It is the largest such barge in the world, containing 8 sidings and using a tug for power and control. The length of loadable train, some 50 cars, would, if the cars were placed end to end, rise up twice as tall as the Chicago Willis Tower. The ferry service started operations in 1962, and has a 3-day voyage between Whittier and Prince Rupert, usually operating once a week, year-round. The Aquatrain barge was built in 1982 by South Korea's Shin-A shipbuilding, and is. Since 1993, the Aquatrain's maritime tugboats and tug crews have been provided by Foss Maritime. Foss utilizes two tugboats Justine Foss and Barbara Foss.
