Fleet cost data


Sydney trains to receive $1.5b boost for services to western suburbs: http://www.abc.net.au/news/2016-12-01/sydney-trains-get-$1.5b-boost-for-services-to-western-suburbs/8083774

Can we get some open data about fleet costs? I feel like we should wait until the lines are driverless and pour our tax dollars into driverless trains, but I have no idea if driverless trains are cheaper in the long run.
