Riding herd on iron horses, with fiber optics; electronic 'eyes' in Omaha watch over trains across the West

Article Abstract:

The Union Pacific Railroad's Harriman Dispatching Center in Omaha, NE is reputed to be one of the world's most sophisticated command-and-control systems for freight trains. Set up in Apr 1989, the center uses fiber-optic communication cables and two-way radio links to monitor the movement of the 800 to 1,000 Union Pacific trains in transit daily. The control center itself cost about $50 million to set up; upgrading communications along the tracks cost hundreds of millions more. The Harriman center now is electronically linked to nearly two-thirds of the railroad's 21,000 miles of track. Union Pacific is currently sharing its expertise with other railroads, such as CSX Transportation Inc and Burlington Northern, because rail carriers depend on each other to complete many hauls.
