ask your dealer for your Railcar number then follow the information in the link below
additional info
I figured I would be calling and getting the status of my truck at least once a day so I programmed a speed dial contact in my phone to check my status (see below), All I have to do is call the contact and everything auto enters in the system. I just have to hit 1 at the end to confirm. this is for Norfolk Southern.
Example, if your railcar info is TTGX702073
TTGX = 8849 on your phone key pad
702073 = the numeric portion of your railcar info
Create a contact like the below example but put your info in.
