Sparks to Weso

Sparks (MP 246.2), is the site of an 8-10 track yard, on the south side of the tracks, and locomotive facilities on the north side along with an Amtrak spur on the north side to the former SP depot on the north side. There is a road bridge overhead, east of the yard, a spur on the south side curving away into an industry, the depot track ends, extra track on the south side, the "Amtrak crossovers", spurs from the extra track curving away into industry on the south side, the extra track curving away into industry, and two road bridges overhead.

Double Track with Automatic Block Signals and Track Warrant Control ends at Vista (MP 249.4), where single-track, CTC, starts, and the speed limit rises from 30-25 to 60 mph, as the line turns from heading east to heading southeast, along the north bank of the Truckee River. There is a detector at MP 251.6, where the speed limit is 70-60, after which the line turns east and crosses the river on a through truss bridge, and passes a road bridge overhead and a dirt road grade crossing just west of the 5,990 ft. siding at Hafed (MP 252.5, where the speed limit is 40 mph, to MP 253.7, where the speed limit is 55-50), past a bridge over a road, Intermediate Signals at MP 255.x, I-80 alongside to the north, and then east-northeast on the south side of the river, all in a river valley with dirt hills along both sides, past the 5,874 ft. siding at Patrick (MP 256.8-258.0), with two dirt road grade crossings within the siding, where the speed limit has risen to 70-60, Wunotoo (MP 260.2), with extra track on the south side, a detector at MP 260.5), as the line turns east to the 5,745 ft. siding at Clark (MP 261.2-262.4), where the line turns east-northeast again, there is a road bridge overhead in the siding, a rail-served plant on the south side, and a grade crossing to that plant, in the siding, near the east end, and then north-northeast across the river, with a line curving away on the east side to an electricity plant on that side.

The line continues along the north side of the river, pasta dirt road grade crossing just west of the west end of the 9,600 ft. siding at Thisbe (MP 265.2-267.2), Intermediate Signals at Salvia, a grade crossing, Derby, another (deck girder) bridge over the river, this time to the south side, two grade crossings, a detector at MP 270.5, Intermediate Signals at MP 272.5, and Gilpin, before the line turns east. There is a north-south mountain range, south of the line and southwest of Fernley, which is on the north side of the line, west of the eponymous siding.

At Fernley, there is a 10,100 ft. siding on the north side (MP 275.3-277.3), where the speed limit is 70 mph, and the SP Modoc Line once left to the northwest. (The original Central Pacific line through this area ran on a more northerly course than the current line, leaving today's line at Derby, and remaining north of the river as far as Wadsworth, and then heading directly across the desert to rejoin today's route at Toy.) The old depot is off to the south, across the road (presumably moved there), along the siding. There is a bridge over a road, just within the east end of the siding, a bridge over a culvert, silos on the south side with double-ended extra track,  near the east end of the siding, part of the town, finally, on the south side, near the east end of the siding, a bridge over a culvert east of the siding, and a road bridge overhead.

In addition to the Modoc Line (which ran through Wadsworth), there was once a connection to the old line trailing in at New Junction, and another one departing to the northeast at Luva, as the main line heads east, with speed limit 70-65, past Argo, Intermediate Signals at MP 278.x, MP 279, a bridge over a culvert, a detector at MP 283.4, and the 9,400 ft. siding on the north side at Darwin (MP 283.5-285.5), with a bridge over a culvert within the siding, turning southeast at MP 284, within the siding, past spurs on the south side serving petrochemical tanks, trailing in, and then east-northeast past a road alongside to the south, and a dirt road grade crossing just west of the west end of the 6,500 ft. siding on the southeast side at Hazen (MP 287.9-289.2), where the speed limit is 75-65, and the Fallon and Hawthorne branches leave to the south, with a bridge over a culvert just east of the siding.

The line heads northeast, through scrubland, past a lake on the southeast side, the 6,185 ft. siding on the southeast side, with extra track on the southeast side, west-facing, at Massie (MP 292.0-293.2), where the speed limit rises to 75-70, a detector at MP 297.0, MP 299, a bridge over a culvert, MP 300, the 10,200 ft. siding on the northwest side at Upsal (MP 301.2-303.1), a bridge over a culvert, and MP 304, and north, along the west edge of the Carson Sink, with mountains off to the east edge of the sink, past Intermediate Signals, a road alongside to the east, a detector at MP 310.0, the 9,600 ft. siding on the west side at Parran (MP 310.2-312.2), a bridge over a culvert, MP 313, a dirt track grade crossing, Intermediate Signals, a river flowing east, three bridges over culverts, Intermediate Signals, a road on the south side, and a grade crossing, after which the Carson Sink is left behind.
