The Invisible Railroad (Again) - Trains Magazine

I'm under the impression that the railroads want to be treated as a utility. Like an underground pipeline.
Most everybody uses gasoline that at one time or another, in oil or gasoline form, went through a pipeline. But I never see any advertizing for pipeline companies.
For advertizing to be effective, it has to connect with the buyer for the product. We, the general public, are not the direct buyers of transportaion. The shippers & receivers are. Any advertizing money that doesn't affect their buying is money wasted.
