A Union Pacific stack train climbs through Bealville, California, amid the green grass and wildflowers of springtime on Tehachapi Pass on March 1, 2016. Powering the eastbound (southbound) train is a trio of GEs—ES44AC No. 8196 leading ET44AC Nos. 2582 and 2613—with the locomotives having just passed through Tunnel 2 and the west switch of Bealville siding.
