Travelers at Denver International Airport (DEN) should prepare for a train service disruption. Maintenance is scheduled for early October. The airport authorities announced that the concourse train will shut down partially for two nights. The trains will operate between Concourses A, B, and C but not from the terminal to the concourses during this time.

The shutdown will occur from 8 p.m. on Tuesday, October 1, to 1 a.m. on Wednesday, October 2. It will happen again from 8 p.m. on Wednesday, October 2, to 1 a.m. on Thursday, October 3. Travelers must use the A Bridge Security checkpoint, located on Level 6 north of the Jeppesen Terminal. Passengers departing from DEN will walk to Concourse A and can access the A gates or take the train to Concourses B and C.

Arriving passengers will do the same in reverse. They will ride the train from Concourses B and C to Concourse A before walking to the terminal. Train service will be available for incoming passengers until 10:50 PM. However, the shutdown will affect departing passengers starting at 8 PM on those days.

Fortunately, passengers with connecting flights will not face disruptions. The train will still operate between the three concourses throughout the maintenance period. This ensures a smooth transit experience for travelers at one of the busiest airports in the world.

Denver International Airport opened in February 1995. It is the largest airport in the Western Hemisphere by land area and ranks as the second-largest airport globally. DEN remains a crucial hub and consistently ranks among the top 20 busiest airports worldwide. In 2023, it served 77,837,917 passengers and contributed nearly $30 billion annually to the local economy.

Currently, DEN supports 25 airlines and offers direct flights to over 215 destinations across four continents. It serves as a major hub for United Airlines and hosts the largest bases for both Frontier Airlines and Southwest Airlines. The airport features one terminal and three midfield concourses, which accommodate a total of 179 gates. Concourse A has 60 gates, Concourse B has 72 gates exclusively for United Airlines, and Concourse C has 47 gates for airlines like Southwest, American Airlines, and Alaska Airlines.

Denver International Airport is known for innovation. It was among the first airports to implement a fully automated baggage handling system. However, this ambitious project faced significant issues and shut down in 2005 after a decade of complications.

As the maintenance approaches, travelers should plan ahead and stay informed about the latest updates regarding train services at Denver International Airport.
