== Elevation Difference Discrepancy == 

 The "Cascade Tunnel" article gives an elevation of 2,881 ft, yet this article says that with a Stevens Pass elevation of 4,061 ft, the Cascade Tunnel is 2,000 ft below it. A simple calculation shows that the difference is actually 1,180 ft, not 2,000 ft (600 m). The photo at the pass shows 4,061 as the elevation there. Unless someone can show that Cascade Tunnel is not at 2,881 ft, then I will change the difference to 1,180 ft (360 m).
