C&NW in Espee country‚Ä¶‚Ä¶Former Chicago & Northwestern AC4400 8806, now Union Pacific's 6708, leads the charge on UP's hotshot 'Lathrop Z' as it hustles across the high desert south of Rosamond.

Three miles back at Oban the Mojave Subdivision hits its lowest point on its desert crossing between famed Cajon and Tehachapi Passes.
