They've been there since that section of the Coast Line between Santa Margarita and San Luis Obispo was built in 1893-94. They were concrete lined in 1910. The line is still on its original alignment, as determined by William Hood, the chief engineer of the SP who also did the Tehachapi Loop.Does anyone know what year(s) each of the tunnels on the Cuesta grade (CS) were built?Tkx
Aboard the Coast Starlight over Cuesta Grade I've always looked away from the mountains to enjoy the great views of the landscape and highway 101 below. Next time (soon!) I'll be checking out the other side of the train, looking at the hill side in hopes of spotting historic remnants of the original line.That makes sense about a large dirt pile inside the abandoned tunnel which I explored.
There's an old water tank that is used to fill up the steam locomotive in that area, toward the hillside. It's partially covered by either trees or shrubs, where the springs are.Aboard the Coast Starlight over Cuesta Grade I've always looked away from the mountains to enjoy the great views of the landscape and highway 101 below.
