A heavy junk train bound for West Colton yard in Los Angeles begin the climb to the summit of Tehachapi Pass and seen here, at Tunnel 2. Two more units, working in DP mode, push on the rear.

Away from Tehachapi mountains and the bad weather, UP 8460 South downgrade into Mojave passing under the old Southern Pacific era cantilever at milepost 377.

UP 7173 South exit Tunnel 10 in Tehachapi Pass with coal empties. The second unit was Southern Pacific 309 still in pure SP heritage. A good catch !
