Awesome post. Think about it. Lot of trains will not leave their immediate area or traverse the same tracks all the time. You are standing still for at least 5 min if you are the first car. It is rolling so multiple people see it. When we are at a train stop, we either watch the rolling cars or are on our phones. It is probably dirt cheap to advertise that way. I never heard of it, but is probably genuine, if the logo is their logo.
