The Queensland Government is planning to transform SEQ’s rail network, with CRR as the first major step. CRR is a north-south rail line in Brisbane’s inner city which features a tunnelled railway under Brisbane’s central business district (CBD) and river, and four new underground inner-city train stations at Roma Street, Albert Street, Woolloongabba and Boggo Road. The proposed scheme consists of approximately 15km of new twin-track railway, of which about 9.5km is to be underground (Fig. 1), between portals at Yeerongpilly in the south, and the Normanby Rail Yards on the Exhibition Loop in the north. Figure 1 shows the key features of the underground section of the proposed Cross River Rail scheme, approximately 9.5km long, with four new underground stations. The tracks pass below the Brisbane River south of the CBD. The scheme passes below the Brisbane River immediately
levels (south is on the left). The local basement rocks are the deep-water meta-sediments of the Neranleigh-Fernvale Beds, which are mantled by Triassic-age tuff (Brisbane Tuff – exposed in cliffs immediately south of the CBD) and sedimentary rocks (Aspley Formation). The city centre is on the northern bank of the river on a point bar, partly underlain by alluvium.
