Mile End

The crossing loop at the Adelaide Parklands Terminal at Mile End is of length 1,658m.

Dry Creek

The first crossing loop north of Adelaide, of length 1,950m, is south of Dry Creek.

Bolivar

The Bolivar crossing loop is 1800 metres long, having been lengthened from 1200 metres in 2012, after the Taylors Road level crossing at the southern end was replaced by an overpass of the Northern Expressway.^[8] As a result, the overpass marks the approximate mid-point of the loop.^{[note 1]}

SCT Penfield

In 2007, it was proposed that an Intermodal Rail/Road facility be built in the Edinburgh Parks area. Accordingly, an area of rural/agricultural land in Penfield was rezoned in 2008.^[10][11]

In the 2010s, SCT Logistics^[12] and another company started to develop an intermodal hub.^[13][14] The new facilities and trackwork commenced construction on the north-east side of the line, south of the Northern Expressway and north of Heaslip Road and RAAF Base Edinburgh, in 2011–2012.^{[needs update]}

Two Wells

The next crossing loop, of length 1,817m, is at Two Wells - the loop is between Gawler Rd and Temby Rd.

Others

There are about a dozen other crossing loops north of Two Wells - refer to the infobox to the right.

Crystal Brook

Crystal Brook includes the triangle junction with the main line to Broken Hill and Sydney. Then there is a 968m crossing loop and siding with provision to load grain at the silos in the town. The tracks converge to single track to cross a bridge over the Crystal Brook, then split into double track for the 20 km to Coonamia. The western track is for northbound travel and the eastern track for southbound, except that there is a balloon loop for loading grain from the AWB silos which is accessed by proceeding a short distance north on the eastern track.^{[15]: 62–66}

Coonamia

Coonamia "station" – in the past a provisional stopping place^[16] but since the early 2010s comprising only a nameboard – is the site of the "0 km" datum point for routes to Port Augusta, Broken Hill and Adelaide.^[15]: 70 At this point ARTC train controllers in Adelaide (who oversee operations between Broken Hill and Coonamia, and Coonamia southwards) hand over to controllers in Port Augusta (who oversee the line to Port Augusta and points west); the sign remains so that train crews can identify the change-over point.^[17] The location has a crossing loop 1638 m (1791 yds) long on the south side of the double mainline from Crystal Brook.^{[15]: 66, 69}

A further 2.25 km (1.4 mi) west is a triangle junction where the double track ends and from which single tracks go west to Port Pirie Yard and north to Port Augusta.^{[15]: 67–68}

Port Germein

The 1960m crossing loop at Port Germein was supplemented by a 805m goods siding in 2015, operated by SCT Logistics.^{[18][15]: 69, 70} A short stub siding also leads off the crossing loop.^[19]
