How Good Is Transperth?

Bag with wallet, keys and phone are inadvertently left on the bus at Whitfords Interchange.
Frantic discussion with Transperth employee.
Both route number and bus number were miraculously memorised.
Bus tracked on dry run on freeway to Perth CBD where driver will take a meal break. No passengers. Maybe he can locate the bag when he reaches his destination.
Oh yes, he does!
If we can meet him at the Central bus station within the hour, we can collect it.
40 minutes. How to get there through peak hour traffic on the freeway?
Hop on the train. We make it with 10 minutes to spare.
Buses are everywhere as commuters make their way home.
Armed with gate number, route number, bus number and time of departure, we meet the bus driver. Bag handed over. A leisurely train ride back to Whitfords.
