KANSAS CITY, Mo. (AP) — Kansas City’s Union Station is marking a 100-year history that has taken it from a bustling train depot to the brink of obsolescence and now to a revived role as a venue for traveling exhibits and massive celebrations.

The Kansas City Star reports (http://bit.ly/1rQlhwG ) an estimated 100,000 people attended the grand building’s dedication in October 1914. Officials are hoping many thousands will also turn out for four days of centennial events beginning Oct. 30.

Hundreds of trains passed through Union Station daily in its early years, but its role declined after World War II as air travel eclipsed rail. The building fell into disuse and decay until it was restored in 1999 with funding from a special tax approved by voters in four Missouri counties and Johnson County, Kansas.
