While googling team tracks I cam across this interesting use for a flat car.
End Ramp. A converted flatcar of 63 foot length serves as a ramp to load and unload from other railroad cars. It ramps from ground level to the standard flatcar deck height above rail. The End Ramp allows transfer of tractors, combines, bulldozers, construction machinery, cranes, and other vehicles. There is room along the ramp for a crane or other equipment used in the tie-down process. It is located at the west end of the North Team Track (car spots N1-N2, additional spots available as needed).
It is located in Semo Port in Scott City, MO.
