Why were TVM's installed on board trains, instead of on the platform, as is the norm in other states ?
1. Because the ticketing system introduced by the STA in 1987 has timed tickets validated on the vehicles rather than location-based tickets validated on the station platforms, and the Liberal government of the time would not have been interested in paying for complete replacement of a system which was still fairly recently introduced and quite cheap to operate.
2. Far easier to have vending machines on what was a fleet of 100 railcars at the time (which could have cash retrieval and servicing done at the depot) than on around 137 platforms at 89 different stations which would have needed additional security resources and a team of crews who would have spent more time driving around than actually retrieving cash and servicing the vending machines. Oh, and would you
have been happy going out to stations like Christie Downs or Smithfield to empty out hundreds of dollars of cash?
