Why wasn’t Santa Fe a granger? 'Cause it ran from Chicago clear to (and directly) Los Angeles and (indirectly to) the Bay Area. This “all-the-way” attribute of its route system made it THE pre-eminent transcon* of its day.
Other roads cited by Murphy Siding:
– UP and NP (and GN, not mentioned) were transcons, not grangers. Carried some grain, to be sure, but they were in it “for the long haul.” (I know–bad pun).
UP was the perfect gatherer of overhead traffic from Chicago to Southern California (via its won rails), the Bay Area (via a friendly Ogden-SP connection), and the Pacific Northwest (own rails, again).
GN and NP competed against each other and UP and (sort of) MILW (see below for added detail) for transcon traffic moving via Chicago and Kanas City to the Pacific Northwest. Together, they originated more farm products than UP, but it was their transcon traffic that kept them solvent.
– SSW served as an extension of parent (98 percent owned) SP, itself a transcon, not hardly a granger.
– MoP derived much of its revenue from its extensive Gulf Coast chemical traffic. Hardly farm product-dependent. Call
