Union Pacific Flatcar No. 51207
Denver County
Union Pacific Flatcar No. 51207 is eligible to the State Register the area of Transportation for both its history as a flatcar that transported freight in Colorado and for its use in an experiment with Trailer on Flatcar (TOFC) style of freight transportation, which ultimately changed out train-transported goods.
Union Pacific Flatcar No. 51207
After Union Pacific constructed the car in Denver in 1951, they modified it in 1954 in order to determine the requirements to place a trailer on a flatcar for service, hence collaborating with trucking companies rather than directly competing with them. Union Pacific used this flatcar in TOFC service until 1967, when they returned it to general service. Union Pacific Railroad flatcar No. 51207 is also eligible in the area of Engineering as an intact example of a mid-twentieth century flatcar, which includes its original friction-bearing trucks.
