Context paragraphs:
Calumet (train): The Calumet, also commonly called the Valpo Local, was a 43.6 mi passenger train route operated by Amtrak between Chicago and Valparaiso, Indiana.  Despite Amtrak's mandate to provide only intercity service, the "Calumet" was a commuter train.  Transferred from Conrail in 1979, the full route was shared with Amtrak's "Broadway Limited" until 1990; the "Calumet" was discontinued the next year.

Carlinville station: Carlinville is a train station in Carlinville, Illinois, United States served by Amtrak, the national railroad passenger system.  Amtrak service is provided by "Lincoln Service" and the "Texas Eagle".  This was also a stop for the "Ann Rutledge" until April 2007.  Service via the "Texas Eagle" in Carlinville is a flag stop; the train will stop there only if there are passengers to board or alight there.

California Zephyr: The California Zephyr is a passenger train operated by Amtrak between Chicago, Illinois, and Emeryville, California (originally Oakland), via Illinois, Iowa, Nebraska, Colorado, Utah, Nevada, and California.  At 2438 mi it is Amtrak's 2nd longest route after the Texas Eagle.  Total travel time from one terminus to the other is approximately 2½ days.  Amtrak claims the route as one of its most scenic, with views of the upper Colorado River valley in the Rocky Mountains, and the Sierra Nevada.

Texas Eagle: The Texas Eagle is a 1,306-mile (2,102 km) passenger train route operated by Amtrak in the central and western United States.  Trains run daily between Chicago, Illinois, and San Antonio, Texas, and continue to Los Angeles, California, 2,728 miles (4,390 km) total, three days a week (incorporated as part of the "Sunset Limited").  Prior to 1988, the train was known as the Eagle.

Carl Sandburg (train): The Carl Sandburg is a 258-mile (415 km) passenger train route operated by Amtrak that runs between Chicago and Quincy, Illinois.  This train began operation on October 30, 2006 and is an addition to the existing "Illinois Service" rail network created in 1971 and partially funded by the Illinois Department of Transportation.  Between Chicago and Galesburg, this train service uses the same triple track (old CB&Q) as three other Amtrak routes: the "California Zephyr", the "Southwest Chief" and the "Illinois Zephyr".  The Galesburg to Quincy route (old CB&Q Quincy/Hannibal main line via Macomb) is served by the "Carl Sandburg" and the "Illinois Zephyr".

Texas Eagle (MP train): The Texas Eagle was a streamlined passenger train operated by the Missouri Pacific Railroad and the Texas and Pacific Railway between St. Louis, Missouri, and multiple destinations in the state of Texas.  It operated from 1948 to 1971.  The "Texas Eagle" was one of many trains discontinued when Amtrak began operations in 1971, although Amtrak would revive service over the Missouri Pacific with the "Inter-American" in 1974.  This train was renamed the "Eagle" in 1981 and finally the "Texas Eagle" in 1988.

Missouri River Runner: The Missouri River Runner is a 283 mi passenger train route operated by Amtrak running between Gateway Transportation Center in St. Louis and Kansas City Union Station in Kansas City, Missouri.  Four trains operate daily (two round trips) on this route: 311 and 313 westbound, and 314 and 316 eastbound.

Sunset Limited: The Sunset Limited is a passenger train that for most of its history has run between New Orleans and Los Angeles, over the nation's second transcontinental route.

Lake Shore: The Lake Shore was a long-distance passenger train operated by Amtrak between Chicago and New York via Cleveland, Ohio.  The "Lake Shore"'s route paralleled that of the New York Central's famed "Lake Shore Limited".  Amtrak introduced the "Lake Shore" on May 10, 1971, nine days after Amtrak had assumed control of most private-sector passenger train operations in the United States of America.  The "Lake Shore" was the only train to serve Cleveland, which had been the largest city left out of the original system.  Amtrak introduced the route on the understanding that Ohio and New York would assume two-thirds of the cost of the train.  The initial plan included a Toledo, Ohio—Detroit, Michigan connection (to be supported by the state of Michigan); Amtrak dropped the planned connection because of poor track conditions between the two cities.

Capitol Corridor: The Capitol Corridor is a 168-mile (275 km) passenger train route operated by Amtrak in California.  Capitol Corridor trains operate between San Jose and Sacramento, roughly parallel to Interstate 880 and Interstate 80.  One train a day continues through the eastern Sacramento suburbs to Auburn, in the foothills of the Sierra Nevada.  "Capitol Corridor" trains started in 1991.
