Mr. Olesen, what I fail to see is any comparison between a railroad crew consist matter and a merger of Chevron and Hess.
First on the roads, so long as there is a parallel highway and if they are willing to accept "being tied up" for at least an hour to get your "highway Conductor" to the scene of, say, a parted air hose, or a hotbox, (of particular interest post-E. Palestine), that's the road's business. In the case of a parted hose, it might even improve efficiency as the Conductor is dropped off at the train's rear and he starts walking forward while the Engineer starts walking rear.
On Hess-Chevron, so what if Hess, a primarily East Coast refiner, wants to hook up with Chevron (nee; Standard Oil of California), what's it to the retail consumer (and voter)?
