call 1-800-877-5123 click option 1 for English's, they say trace when they ask and speak your railcar number they will ask for fax i say no, all it said for me since i started to track it was, shipped and date, or arrived and date, but never told me any location.
so really it was pointless.
actually i have heard that red car insurance is a little more because it calls out attention. also for police since you can see from long distance. and cant blend in the traffic.
