Editing Sidney, Ohio (section)

===Rail===
Sidney has two railroad lines. Both were built independently in the 1850s.

Until the 1960s, passengers could take the Knickerbocker Limited from Sidney to [[Grand Central Terminal]] in New York City. This east–west line was built as the Bellefontaine and Indiana Railroad which ran from Galion, Ohio to Union City on the Ohio-Indiana border. It was built in conjunction with the Indianapolis and Bellefontaine Railroad, providing a route between Cleveland and the East and Indianapolis, and later St. Louis. In 1864, the two were merged into the "Bee" Line: the Bellefontaine Railway. In 1869, the lines were merged into the first "Big Four": the Cleveland, Columbus, Cincinnati and Indianapolis Railway. In 1889, the second "Big Four" was formed: the Cleveland, Cincinnati, Chicago and St. Louis Railway. In the early 1920s, this railroad relocated its tracks from downtown Sidney to the south edge of the city over the new Big Four concrete arch bridge. Early in the twentieth century, it was leased by the New York Central System. Later the Big Four was taken over by the Penn Central, then Conrail, and finally [[CSX Transportation]].

Other concrete arch bridges in the region were designed and built for the Big Four; they are located in [[Avon, Indiana|Avon]] and [[Greencastle, Indiana]], and [[Danville, Illinois]].

In the 1950s, passengers could board a train in Sidney and take it south to Cincinnati or New Orleans. This north–south line was built as the Dayton and Michigan Railroad. In the 1860s it was leased by the Cincinnati, Hamilton and Dayton Railroad. It was taken over by the [[Baltimore and Ohio Railroad]] early in the twentieth century. Later the line was taken over by the [[Chesapeake and Ohio Railway]], then by CSX Transportation, and passenger services were reduced.
