or, leave it as it is because the amount you save on evaded fares prob wouldnt hit anywhere near $1m a year so you'd be running a loss as well as bothering thousands of passengers with digital scanners. How would it even work? You have to remember which card you used to pay then they scan it to see if it's been used on the system in the last hour or so? By the time you get through 3 passengers, every fare evader has tapped their card or jumped off at the next stop.Or, hear me out: Hire 10 fare inspectors, 5 for the GLX and 5 for the western surface branches. Loudly ticket fare evaders. The threat of public confrontation would be enough to get 97% of people to pay. At $100k/yr each it would take a thousand years for them to cost as much as a $1B fare gate installation project.
Shouldnt have bothered upgrading the payment system and just made the subway/light rail free.
