The experimental trains of Colorado: remnants of a failed technology

The city of Pueblo, in Colorado (USA), owes much of its development to the railways. Some very advanced for their time were tested there.

The urban explorer Bob Thissen has been able to see and enter them, and has shown them in a video published a few days ago on his always interesting YouTube channel Exploring the Unbeaten Path:

You can see some screenshots of the video below. Perhaps the most impressive of these experimental trains is this prototype of the Rohr Tracked Air-Cushion Vehicle (TACV), an electric train designed to run on a monorail on a cushion of air. It was tested in Pueblo, and after the failure of the invention, the manufacturing company donated it to the city in 1977 with the condition that it be exhibited in a museum. It was taken to the Pueblo Aircraft Museum, and in 2008 it was donated to the Pueblo Railway Museum, always remaining outdoors. In total it has been outdoors for 45 years:

Sadly, the interior of the TACV has been deteriorating due to the passage of time and due to the lack of a suitable place for its exhibition:

Another of the experimental trains exhibited in Pueblo is the Linear Induction Motor Research Vehicle (LIMRV), a wheeled vehicle designed to circulate on conventional tracks, powered by two Pratt & Whitney J52 jet engines, c Achieving a world rail speed record of 411.5 km/h on August 14, 1974. As you can see, it is in a sorry state of preservation.

Finally, in Pueblo you can also see the Grumman Tracked Levitated Research Vehicle (TLRV), from 1970. A train that looks like a spaceship. Like its other two weather companions, it was very advanced technology for its time and failed due to its high cost and impracticality:
