This clip features three trains at Tunnel 2 at the bottom end of the Bealville siding along UP's Mojave Subdivision in the Tehachapi Mountains.
First up, from atop the tunnel we catch an uphill BNSF Z train. It'll end up stopping at the top end of Bealville to await downhill UP traffic, the first of which is a Z train which is also caught from atop the tunnel. The second train is a UP manifest which we view from track level.
