At Squamish (MP 40.4), where Mount Garibaldi overlooks the scene, there are docks on the west side of the line, a 10,670 ft. yard siding and a 7,270 ft. station siding, a spur heading south-southwest, a passenger station on the west side of the line, and the road's Squamish Shops, also on the west side of the line, the single track, OCS line, with overall speed limit 55 mph for passenger trains and 35 mph for freights, but a local speed limit of 45/25, turns away from the water, just east of due north, past MP 42.4, where the local speed limit rises to 45/35, with a passenger restriction of 40 mph across the road crossing at MP 42.4 and a detector at MP 44.4, and starts to climb the 2.2% grade up the coastal mountains, at Brackendale (MP 44.6), turning northwest, north and northeast, past Cheekeye, where it comes alongside the Cheakamus River and turns curvily north, the 6,600 ft. siding at Cheakamus (MP 50.0), MP 50.8, where the local speed limit drops to 35/20, a detector at MP 51.7, a tunnel at MP 53.5, a detector at MP 54.6, Swift (MP 55.1), and tunnels at MP 55.4 and MP 55.5. Much of the climb has the line running in a narrow gorge alongside the raging whitewater Cheakamus River, including a spectacular bridge at MP56.5.
The line then passes Watson, a detector at MP 58.5, the 6,600 ft. siding at Garibaldi (MP 59.7), where it starts to run along the west side of beautiful alpine Green Lake, detectors at MP 61.1 and MP 61.6, Water Tank (MP 62.7), Pinecrest (MP 63.6), a detector at MP 65.5, Brandywine Falls, where there is a high waterfall that can only be viewed from the line (unfortunately, from behind, at the very top), the 6,940 ft. siding at McGuire (MP 67.4), north end of the lake, where the line turns curvily northeast, Alpha (MP 70.4) and a detector at MP 72.9 to Whistler (MP 73.7), a famous alpine skiing resort, where the regular passenger trains stop. Just north of Whistler, the speed limit increases to 45/35 at MP 74.2, past Alta Lake, a summit at 2,099 ft. elevation, Canadian Hostel (MP 75.3), and the 6,900 ft. siding at Mons (MP 77.4).
The line then and starts the 2.2% descent at MP 78.5, where there is a detector and the speed limit drops to 40/20, past Parkhurst, Wedge (MP 81.4), where it turns curvily north, a detector at MP 85.1, Green River (MP 86.5), a detector at MP 87.9, and the 7,200 ft. siding at Tisdall (MP 90.4), where it turns northeast, with a speed limit of 30/15 between MP 91.5 and MP 92.0 until the track is seen to be clear, otherwise 40/20 as before and subsequently, to the 1,810 ft. siding at Pemberton (MP 95.0), the helper station for the southbound upgrade, which has a wye and a speed limit of 25 mph on a road crossing, where it bridges the Lillooet River and turns east.
North of Pemberton, with the speed limit now 45/30, the line crosses through a mountain divide (in the Cascades) past Mount Currie (MP 99.4), where it turns curvily north, following a river valley upwards, on the west side of the river, past MP 100.4, where the speed limit drops to 40/20, a detector at MP 101.1, Owl Creek, a bridge to the east side of the river, Spetch (MP 103.7), MP 105.4, where the freight speed limit rises to 25 mph, the 7,200 ft. siding at Creekside (MP 106.5), Pool Creek, where it turns away from the river and follows the eponymous creek north-northeast, Gramsons (MP 109.6), a turn east-northeast, past the end of the creek, MP 110.6, where the freight speed limit drops to 20 mph again, and a summit (of the Cascades) at an elevation of 1,612 ft., and starts to follow the Gates River downhill towards Lillooet and the Fraser River valley, past the 7,200 ft. siding at Birken (MP 112.6), a detector at MP 114.5, MP 116.4, where the freight speed limit rises to 25 mph, a detector at MP 117.0, Gates (MP 118.0), a bridge across the river to its east side, Devine (MP 120.6), where the line turns curvily north, a bridge back to the west side of the river, and the 6,390 ft. siding at D’Arcy (MP 122.9), on the shores of Anderson Lake, where the helpers are added for the two southbound upgrades.
The line then passes along the west side of the large Anderson Lake, heading generally north-northeast, past MP 124.0, where the freight speed limit drops to 20 mph on the ledge along the lakeshore, a detector at MP 125.0, Scott (MP 125.3), a speed restriction of 25/15 until the track is seen to be clear, between MP 125.5 and MP 126.0, for the tunnel at MP 125.6, and 40/20 otherwise and subsequently, Ponderosa (MP 128.0), where it turns north, a detector at MP 128.4, McGilvray Falls, and McGilvray (MP 129.1). Along here, for example at the 1,505 ft. siding at Marne (MP 130.6) on Anderson Lake, and again along Seton Lake, the line is often running along a ledge alongside the lakes, and is the only means of access to some small communities alongside the lakes. Children use the rail service to get to and from school in Lillooet, using a special train (named the “Buddwiser”) in the morning and the regular passenger service to return in the afternoon.
The line continues northeast along the lakeshore past Bedrock (MP 132.5), Curries (MP 134.1), a detector at MP 135.0, a speed restriction of 25/15 between MP 135.2 and MP 135.6, a speed restriction of 25 mph for passenger trains between MP 136.4 and MP 137.7, through Whitecap (MP 137.0), Buntains (MP 137.9), a speed restriction of 20 mph for passenger trains at the road crossing at MP 138.4, and the 6,300 ft. siding at Seton (MP 139.5), at the northeast end of the lake, across Seton Portage between the lakes to the north side of the large Seton Lake, heading curvily east following the lakeshore, where it passes a tunnel at MP 140.6, the Bridge River BC Hydro plant, South Shalalth (MP 141.4), Shalalth (MP 142.4), Chin (MP 143.6), a speed restriction of 35/15 between MP 146.8 and MP 147.7, a detector at MP 174.5, the 6,435 ft. siding at Retaskit (MP 149.2), a speed restriction of 25/15 between MP 150.6 and MP 150.9, Craig Lodge, a passenger speed restriction of 25 mph between MP 151.8 and MP 152.1, a detector at MacNeill (MP 152.3), and Seton Creek at the east end of the lake.
The line now follows the north side of the river exiting the lake, past a passenger speed restriction of 25 mph between MP 153.6 and MP 154.5, where the original Pacific Great Eastern line along here continued east to cross the Farser River and today's line turns north-northeast, past a large lumber mill and the start of Yard Limits at MP 155.5 into Lillooet (MP 156.3 to MP 157.6), where there is a yard extending between the two mileposts, and the depot is on the west side at the latter, where the speed limit is 35/20. At MP 157.8, north end of the yard, there are speed restrictions of 10 mph heading northward, and 20 mph heading southward, after which the speed limit returns to 35/20. Yard Limits end at MP 158.5, and there is a speed restriction of 30 mph for passenger trains for an overbridge between MP 160.1 and MP 160.4, with the speed limit again returning to 35/20.
North of Lillooet, the line runs north-northeast alongside the Fraser River, on its west side, then cross it on a spectacular bridge to Polley (MP 160.3), where the original PGE r-o-w trails back in on the east side, and start to climb the east wall of the canyon, heading north. The line runs on a narrow ledge and eventually climbs to almost 2000 feet above the river, far below, along the way turning east, following a turn in the river, south past past Fountain (MP 165.3), east, northeast past a tunnel at MP 168.4 and Gibbs (MP 169.0), and north again past the 7,100 ft. siding at GlenFraser (MP 172.8), a detector at MP 175.3, a turn northeast into a side valley, the 625 ft. siding at Pavilion (MP 177.9), a counter-clockwise horseshoe back west, and then north along the ledge above the Fraser River again, past the 7,065 ft. siding at Moran (MP 181.0), a detector at MP 183.0, and Fowler (MP 184.5).

The high point along the line is at an altitude of 3,865 ft., at (Horse Lake) Summit (MP 244.0), after which the line makes a counter-clockwise horseshoe to the west and then a clockwise horseshoe to the northeast before turning northwest at Lone Butte (MP 246.2), where there is still an interesting water tank next to the line, past Norris (MP 248.0), some curves back and forth through Canim (MP 252.7), a detector at MP 253.8, a turn just north of due west, a detector at Edmund (MP 256.1), a clockwise horseshoe back to the east, Ainsworth Lumber, and MP 259.0, where the speed limit returns to 55/35.
