Well, except for that solar panel on the relay pole 
@renfe130 Perdona mi español. En invierno, utilizan locomotoras extra en caso de mal tiempo. Además, el tren pesa más de 1.280 toneladas en lo que 17.000 caballos de fuerza no es mucho cuando se sube la Cascades y las Rocky Mountains.
English: The Empire Builder often uses 4 P42s in the winter. Frequent storms drop up to 2 meters of snow in the Cascades and temperatures in Montana of -30C are common. The extra power is insurance and even so, the Empire Builder is late almost every day during the winter. This train weighs over 1280 metric tons so 17,000 horsepower really isn't that much.
