Considering the rapid growth of the Yarrabilba area combined with southern parts of Logan such as Marsden and Browns Plains as well as southern Brisbane City suburbs like Calamvale and Forest Lake having poor access to the rail network, I am proposing a 31.45km rail link, branching off from the Springfield line south of Richlands. This new line would have a total of 8 new stations:
- Forest Lake
- Heathwood
- Calamvale
- Marsden West
- Heritage Park
- Koplick Road
- Logan Village
- Yarrabilba.
Considering lack of capacity along the Salisbury - Dutton Park Corridor especially post CRR and the greater need to service Yarrabilba and other growing suburbs, I have decided to pair the alignment with the Western Lines (T1 Ipswich and T2 Springfield), to take advantage of existing quad tracking between Darra and Milton.
Considering it’s already roughly 19.5km from the city to Richlands by rail and this line would branch off 2.8km south of Richlands, the overall distance from the city to Yarrabilba would be about 53.75km. For comparison the Caboolture is about 45km from the city and Beenleigh is about 40km.
This new line would be served by T3 services with some services going beyond the city to Doomben. Estimated Journey time from Central to Yarrabilba would take about 70-80 minutes if services were to remain stopping all stations or about an hour if an express service was implemented.
