In 1993, the Southern Pacific Railroad (which operated the CPRR-built Oakland–Ogden line until its 1996 merger with the Union Pacific) closed and pulled up the 6 miles section of Track #1 over the summit running between the Norden complex (Shed 26, MP 192.1) Norden at coord and the covered crossovers in Shed #47 (MP 198.8) Shed 47 visible at coord about a mile east of the old flyover at Eder, bypassing and abandoning the tunnel 6–8 complex, the concrete snowsheds just beyond them, and tunnels 9–12 ending at MP 195.7, all of which had been located on Track 1 within two miles of the summit.
