Big Boy No. 4014 Coast-to-Coast Tour Public Display

Union Pacific's famed Big Boy No. 4014, the world's largest operating steam locomotive, will journey to the East Coast this summer for the first time as part of a historic coast-to-coast tour to celebrate America's 250th anniversary. The tour includes a Fourth of July celebration in Philadelphia, major display events in eight cities and more than 50 whistle-stops in 10 states, including stops for the first time in Indiana, Ohio, New York and Pennsylvania.

In addition to the public display days, rail fans can see this historic machine in action at over four dozen whistle-stops, generally 15- to 30- minutes long.
