Dotsero to Orestod (Bond)

Between Dotsero and Orestod, the train traverses the Dotsero cutoff, built in the 1930s to connect the D&SL and the existing Denver & Rio Grande Western line across Tennessee Pass, through yet more canyons, to the junction at Orestod and Bond. From the 6,150 ft. siding at Dotsero (MP 343.4-342.0/166.8), where the Tennessee Pass line (or what's left of it) heads east at a wye, following the Eagle River, the present-day main line takes the Dotsero Cutoff to the north, following the east bank of the Colorado River, curving northwest past a detector at MP 166.3, north past Intermediate Signals, Niche, east, north, with a slide fence on the east side, and northeast past a slide fence on the east side to 1,115 ft, Sweetwater Tunnel (MP 159.2), with another slide fence on the east side at the north end of the tunnel, north past a bridge over a road, Sweetwater, north-northeast past a detector at MP 157.1, where the speed limit rises to 55 mph, a dirt track grade crossing, a detector at MP 156.1, and the 7,720 ft. siding on the east side at Range (MP 156.0-154.3), with a dirt track grade crossing in the siding, and extra track on the east side and another dirt track grade crossing near the north end, a dirt track grade crossing north of the north end, then very curvily along the river north-northeast  at 35 mph, past a dirt track grade crossing, a bridge over the river to the west side, a bridge over the river back to the east side, a bridge over the river to the west side again, and Sylvan.

The line turns northeast, past Intermediate Signals, a bridge over the river to the southeast side, a detector at MP 148.4, Intermediate Signals at MP 147.0, and Burns, east, north past Intermediate Signals at MP 145.4, a bridge over the river to the west side and over a dirt road, east past Intermediate Signals just before a bridge over the river to the south side, south past Intermediate Signals, east and north within the 7,430 ft. siding on the south/east side, with extra track on the south side near the west end, at Dell (MP 142.6-141.1), where the speed limit rises to 40 mph, a bridge over a small side stream, and a rock wall on the south/east side with the river on the north/west side, across the river to its west side just "east" of the "east" end of Dell, and turning east, with the river and a dirt road on the south side, past a dirt road grade crossing, a deck girder bridge over a side stream, and Intermediate Signals at MP 137.5, northeast, east, north past a dirt road grade crossing and Intermediate Signals at MP 136.7 to Glen, south-southeast past a bridge over a small stream, and east to Intermediate Singals at McCoy PO, south, with a pipe bridge overhead, east past a dirt rack grade crossing, southeast through 647 ft. Yarmony Tunnel (MP 131.2), and south-southeast at 55 mph, bridging across the river twice, to the beginning of an 11,750ft. siding at West Bond (MP 130.8), with the river on the south side again, curving south, and reaching the junction with the Craig line (original Denver & Salt Lake route, now a major coal originator), which climbs away westward on the north hillside, at Bond (Orestod), MP 128.8, where the speed limit is 25 mph.
