Sunset Limited
The "Sunset Limited" was the premiere SP train on the "Sunset Route" — and probably on the whole SP system — and the "Argonaut" was a slower secondary train. The "Argonaut" needed fifty hours between New Orleans and Los Angeles, while after 1950 the "Sunset Limited" needed forty-two. The Argonaut ran Tucson to El Paso via Deming; the westward train usually ran on the EP&amp;SW line via Douglas.
