UP 1943 on Cajon Pass!
https://railfanjunction.carrd.co/
On two separate occasions in 2022 and 2023, UP 1943, the Spirit of Union Pacific Heritage Unit, led a manifest up and down Cajon Pass on both main lines! Our cameras caught it descending the Palmdale Cutoff at Canyon and Rialto and then ascending up the north track at Sullivan's Curve and West Summit!
