BNSF 6932 heads up an eastbound stack train descending Stevens Pass at the east switch of Berne, WA, MP 1697. The train is passing under a rare former Great Northern signal bridge. Two DPUs bring up the rear. The eastside grade from the Cascade Tunnel to Merritt, WA is only about 7 miles, but still requires careful train handling and plenty of horse power and dynamic braking.
