Except in New Jersey, full-service gas stations where someone comes out and fills up your vehicle have rapidly vanished from the American landscape.
But on the railroad, it is common for someone to top off the tanks of locomotives with diesel fuel. And so it is with Amtrak.
At many intermediate stations on the Amtrak network, a fuel truck drives up before the arrival of a train and the driver gets out and puts diesel fuel into the locomotive tanks.
It is routine that is not practiced in all that many places when you consider how many stations that Amtrak has.
But it is train time ritual nonetheless and one that gets little attention from passengers or railroad photographers.
This particular scene unfolded in Sacramento, California, on June 26, 1999, as a worker fills the tanks of the Los Angeles-bound Coast Starlight.
