Weso to Alazon, Track 1 (ex-SP)

At Weso, just east of Winnemucca, the paired track with the former WP starts and continues eastward through the Humboldt River valley, sometime widely spaced, sometimes close. CTC ends at Weso, and the line continues as "Double Track" (i.e. the Paired Tracks), Automatic Block Signals. This description covers only Track 1, the original CP and later SP line.

From Weso (MP 420.9 on this track), the line turns east, with speed limit 70-60, past a spur heading away on the south side, and Tule (MP 422.8), and then southeast, past I-80 adjacent to the south, for a short distance, a dirt road grade crossing, a detector at MP 427.3, where the speed limit is 55-50, a spur at Golconda (MP 434.0), where the speed limit rises to 70-60 again, and the line turns curvily east, a detector at MP 437.7, the Humboldt River alongside to the south, an acute angle grade crossing, and Preble (MP 439.3), one of two locations where the line has been relocated northward from the original CP alignment. The line turns southeast, past a deck girder bridge over the river, Iron Point (MP 448.1), a detector at MP 452.0, where the second relocated section starts, a grade crossing, a spur on the south side at Valmy (MP 457.5), where a connector from the place of the same name on the ex-WP line connects in on the north side, a dirt road grade crossing, I-80 parallel off to the south, a spur at Mote (MP 465.3), a detector at MP 469.9, and the 6,500 ft. siding at Battle Mountain (MP 475.8), where the line turns east again, and the 3 ft. gauge Nevada Central once left to the south.

There was once a detector at MP 479.7, the line turns north-northeast to the spur at Argenta (MP 487.7), east past a detector at MP 491.0, where the speed limit has fallen to 60 mph, Mosel (MP 492.9), Jayhawk (MP 497.7), where the speed limit rises to 79-60, and Shoshone (MP 498.3), where the line turns south, past the location of a former detector at MP 498.6, and south-southeast to Beowawe (MP 508.2), where the speed limit drops to 55-50, Track 2 comes quite close on the north side, and there are crossovers between the two. The line curves east, past a detector at MP 512.5, into Palisade Canyon, where the speed limit falls to 50 mph, past Harney (MP 517.0), and the crossovers at Barth (MP 520.3).

The line crosses over the Humboldt River, passes beneath the ex-WP line (Track 2), turns northeast, crosses the river again, crosses the route of the former narrow gauge Eureka & Palisade, passes through 874 ft. Tunnel 1 (MP 525.2), crosses the river again to remain on the north side as far as Tulasco, crosses the  former narrow gauge r-o-w again, and passes the spur at Palisade (MP 525.7) into Carlin Canyon. There is a detector at MP 529.7, where the speed limit is 50-45, and crossovers at Carlin (MP 534.5), where the speed limit is 25 mph and there is an 8,660 ft. center siding. The line turns east, past Vivian (MP 537.5), where the speed limit is 79-60, and the location of Tunnel 2, and east-northeast past Moleen (MP 544.7), where the speed limit is 60 mph, a detector at MP 547.6, where the speed limit is 70-60, West Elko, Elko Amtrak Station (MP 557.0), where the speed limit is 70-65, Elko Yard, crossovers at MP 559.3, where there is a 5,430 ft. siding and the speed limit rises to 70 mph, Elko (MP 560.0), and a detector at MP 563.0, where the speed limit falls to 60 mph. 

The line turns east at Osino (MP 564.8), and passes 2,473 ft. Tunnel 3 (MP 566.6), Ryndon (MP 568.4), and 3,917 ft. Tunnel 4 (MP 569.4), turns northeast past crossovers at Elburz (MP 573.1), where the speed limit rises to 70 mph, the former location of a detector at MP 574.0, crosses the North Fork of the Humboldt River, passes Halleck (MP 576.7), and a detector at MP 581.0, and turns just north of east past Deeth (MP 589.6), where there is a crossover to Track 2 and the speed limit is 70-60, and the current routing takes up a path further south than the original CP right-of-way, a spur at Telasco (MP 594.1), where the speed limit rises to 70 mph, a detector at MP 599.0, where the line crosses over the Humboldt River, and east to the crossovers at the end of Paired Track at Alazon (MP 603.6).

The line separation is five miles further east at Wells.
