Ford chat gave me the railcar number. From there, you can call, in my example, CSX at 800-235-2352. Press 1 to get location, then enter the alpha characters for the car number. For example, the letter "T" is the 8 key, followed by the position of the letter on the key. In this case, "T" is the 1st position on the number 8. So for the letter "T" the numbers entered would be "81". Then enter the digits of the railcar number. The voice prompt will ask you if you need to enter another car or say done. It will then give you the last marked location of the car, the date and time of that location. I hope this helps.
