Denver International Airport will receive 19 new automated people mover train cars, allowing for the decommissioning of older vehicles and increasing its fleet size, the airport said Friday afternoon.

The contract for the order of train cars, manufactured by the company Alstom, is valued at $69.9 million, and comes off the back of an initial order for the vehicles back in 2018, according to DIA.

“We are delighted to see how Denver International Airport has grown over the years and proud to be a partner with them as they manage an increasing number of passengers that move through the airport each day,” said Michael Keroullé, president of Alstom Americas, in a news release on the company’s website.

Both orders are part of the airport’s Automated Guideway Transit System revitalization program, aimed at increasing passenger carrying capacities and improving energy efficiency on the train cars that run between the different terminals, according to a July 2024 news release. 

The first order in 2018 was for 26 new vehicles, replacing 16 that had been in operation since the airport’s construction and increasing its fleet size to a total of 41, allowing for the operation of eight total trains and increasing the system capacity by about 13%, DIA said Friday. The final vehicle from that initial order is expected to be delivered later this year.

This new order will replace the remaining aging vehicles and increase the fleet size to 45, the airport said.

The airport set an all-time passenger traffic record of 82.3 million in 2024 and is projected to exceed 100 million passengers per year by 2030, according to the release from Alstom.
