The other night I was boarding Metrolink in Fullerton to head home to Irvine and saw a BNSF Passenger train. A couple recent looking cars, a handful of polished aluminum looking classic cars and at least one dome car. I saw a couple of reflective vest and badge wearing gentlemen detrain and asked them what was going on. They said it was a marketing trip coming back from San Diego. I thought a moment and then asked what passengers they were marketing to since they are a freight line. Aha, took me a second - marketing to buyers of rail freight. Anyways, just thought it was kinda interesting. Oh, I have a bad pic of the dome car, but don't know how to post from my phone.
