Montana's first railroad, the Utah and Northern, entered the state in 1880. Today, Montana is served by two Class I railroads (Burlington Northern and Santa Fe, and Union Pacific), two regional railroads, and three local railroads, operating on 3,310 rail mi (5,326 km) of track. Amtrak operates one long-distance route (Chicago–Seattle/Portland) through the state, which serves 12 stations.
Because of its large size, small population, and difficult terrain, Montana was slow to develop a highway system. In 2000, the state had 69,567 mi (111,957 km) of public roads, streets, and highways. There were 1,052,737 registered motor vehicles in 2000, including 466,659 automobiles, 556,772 trucks, and 2,795 buses. There were 678,899 licensed drivers in the same year.
Montana had 222 airports, 28 heliports, 2 stolports, and 2 seaplane bases in 2002. The leading airport is at Billings, with 346,375 passengers enplaned in 2000.
