The 150th anniversary of the Golden Spike at Promontory Point, Utah was May 10, 2019. But the final Golden Spike that completed the railway to the Pacific was held in Niles Canyon, CA. this afternoon the Niles Canyon Railway observed the anniversary with a recreation of driving the Golden Spike. I was invited to observe the event by my old friend Peter Midnight.
This is probably the only time I will see two standard gauge Mallet locomotives on the same railway.
