Situated adjacent to Harris park station, Parramatta Rd., M4 and the Great Western highway the Parrahub building will have 15,000 free parking spaces and 2,000 units with shop/office space in the centre and 24/7 restaurant on the top floor. |
|
At the base of the car park will be 24 mini subways to suburbs including Gosford, Lithgow and Wollongong. Also there would be plenty of room to terminate any heavy rail, Metro or VFT there. |
|
Although a conventional TBM could drive all these tunnels a distance of 200m per day for $3,000/m, I believe the Parrahub LTBM with diamond coated picks has the potential to drive 1km per day at $500/m in Sydney. |

The new design crossflow carriages will still be battery powered with an 80kph tailwind assist provided by a 100 m3/s fan located between the tunnels either end but will have the added advantage of consisting of up to 10 twenty metre cars with passengers boarding and exiting the train simultaneously. |
|
20m wide ramps will allow 5,000 cars per hour in either direction simultaneously in the 15,000 space underground car park. |
