These locos and the train they're pulling are now long gone from Cajon. Santa Fe PA-1 #67 is leading a brace of Alco bretheren pulling the westbound Fast Mail Express across the crest of Cajon Pass. This train, which up until its demise featured fifteen to twenty-five heavyweight cars of a variety of roads, met an untimely end when the U.S. goverment withdrew Santa Fe's mail contracts. The classic PA'S followed the Fast Mail into oblivion last year.
An eastbound Santa Fe freight, lead by SD-24 #916 and five more road units, winds through the final curve leading into the railroad settlement of Summit at the top of Cajon Pass.
A few minutes later DL-600B #847 leads the way for an 80+ car train on the westbound tracks. It's a 2.2% downhill grade from here before reaching flat land.
Meets are not uncommon on the double trackage that winds through Cajon carrying Santa Fe and Union Pacific trains. Here the motive power of an eastbound UP train passes by the caboose of a westbound freight in another scene shot at Devore.
Southern Pacific SD-35 #6927 leads a brace of EMD sister units pulling an eastbound freight over Espee's new Colton-Palmdale cutoff line through Cajon. At Summit the Espee line passes within one hundred yards of the ATSF-UP main lines, and it's possible to see trains of all three main western railroads at this one spot.
