PHILADELPHIA - The largest operating steam train known as ‘Big Boy’ will visit Philadelphia on the 4th of July, drawing thousands of train enthusiasts to the city to see the historic locomotive.
What we know:
Union Pacific's Big Boy No. 4014 is doing its first-ever tour of the northeast in honor of America's 250th Birthday. Big Boy started its journey in Cheyenne, Wyoming on May 25 and will make stops in 14 states by July 29.
The large locomotive will arrive in Philadelphia on July 4 before heading back west on July 5.
The 133-foot-long train won't be traveling alone. Taking the trip as well are two commemorative locomotives, No. 1616 Abraham Lincoln locomotive and No. 1776 America250.
Historical passenger cars from the Union Pacific's Heritage Fleet will also make an appearance.
Dig deeper:
Big Boy's appearance in Reading, Pennsylvania drew several thousand people on Thursday as temperatures exceeded 100 degrees. Officials say operational delays caused Big Boy to arrive over an hour late, creating hazardous conditions for those in attendance.
Big Boy locomotive: More than 100 people treated for heat-related incident at Reading Railroad station
A mass casualty incident occurred during a public event featuring the Big Boy steam locomotive in Muhlenberg Township, prompting a large-scale emergency response.
Over 100 people, including the elderly and infants, received medical treatment, and 35 patients were taken to a local hospital for evaluation. Officials say one person suffered cardiac arrest and was successfully resuscitated.
The backstory:
The locomotive is just one of 25 which were commissioned starting in 1941.
Used to support the World War II effort, the trains typically operated from Utah to Wyoming, hauling heavy equipment.
The train which will be traveling to Philadelphia, No. 4014, was retired at the end of 1961 after totaling over one million miles.
Seven of the 25 locomotives are on public display throughout the United States.
