That toll system is a joke too. It's too expensive to use for average people which is why a 30 mile commute is close to 90 minutes. and they keep building out west and south of the city.
The problems with Metro owe a lot to the fact the system was started in the early 70’s and much of it was designed with a 50 year service life. That the prior administrator of the system tried to make the books look better by deferring maintenance, along with too much of that maintenance being done wrong only makes an expensive situation worse.
