Coomera to Helensvale rail duplication

This project involved the duplication of the last remaining section of single track, approximately 8.2km in length, on the Gold Coast line between Helensvale and Coomera.

Golding had previously completed duplication projects for QR north and south of this section. Many staff from these earlier projects were able to re-use their valuable experience again in the Rail Corridor – a very tight high risk environment.

Adjacent train speeds of up to 140km/hour were maintained while constructing adjacent bridges at 4 metre centres.
