Composite image of <a href="https://en.wikipedia.org/wiki/Donner_Summit" class="extiw" title="en:Donner Summit">Donner Summit</a> and <a href="https://en.wikipedia.org/wiki/Donner_Lake" class="extiw" title="en:Donner Lake">Donner Lake</a> with the <a href="https://en.wikipedia.org/wiki/Central_Pacific_Railroad" class="extiw" title="en:Central Pacific Railroad">CPRR</a> grade visible on the right exiting the Summit Tunnel (Tunnel #6) passing through Tunnel #7 and entering Tunnel #8. The upper image, which was taken c1869 by A.J. Russell, shows the grade covered by wooden snow sheds. The lower image was taken by the uploader (<a href="https://en.wikipedia.org/wiki/User:Centpacrr" class="extiw" title="en:User:Centpacrr">Centpacrr</a>) in August, 2003, which shows where the rails of Track #1 had been in place and in daily use from 1868 until the 6.7 mile section of Track #1 between Shed 26 (MP 192.1) and Shed #47 (MP 198.8) about a mile east of the Eder flyover was removed by the <a href="https://en.wikipedia.org/wiki/Union_Pacific_Railroad" class="extiw" title="en:Union Pacific Railroad">UPRR</a> (which now owns the grade) in 1996. All traffic over the summit moved since then over Track #2 about one mile south of Donner Pass and crosses the summit through the 10,322-foot long Tunnel #41 (built in 1925) running under Mt. Judah between Soda Springs and Eder. (The west portal of the Summit Tunnel appears in the lower right corner of each image.)
