Remarks: Approaching Tunnel 2 on the eastbound climb over Tehachapi, a trio of GP50’s and a pair of somewhat rare predecessor GP40X’s has throttled down, creeping a restrictive signal that finally flips to red over yellow. Careful attention to the audio reveals that Run 8 is achieved as the two trains are passing. The headend is about six car lengths out of the scene when another GP50 and two GE B40–8 “Toasters” cut in mid-train become distinctly audible as they emerge from the tunnel. Once the eastbound is out of the way, the westbound continues its descent toward Bakersfield.
