It's a bit surreal, watching CNN at the CA. In the last hour, I've seen a Norfolk Southern ad, a CSX ad, and just now a a Union Pacific ad. It's kind of amusing seeing railroads "duking it out" like this...any idea what's behind them getting into a bit of an ad war, though?
I see it as more of a branding campaign by the freight RRs to build awareness of the value & efficiency of rail transportation and to associate those specific companies with that. The average consumer really doesn't have a whole lot of interaction with freight RRs or how they fit into the distribution of both bulk and consumer goods.
Of course, there's nothing wrong with a good healthy rivalry either. Wonder where BNSF's national ad campaigh is?
