CAT has many high points. The system is easy to use. They use a numbering system similar to MTA's. South, the 400 series are services which operate only until the evenings, and community circulator Line 701. The service is laid out on a grid, also similar to L.A. County.
Transfers are free, and can be used twice.
All but four routes operate until 1 a.m., and everything runs seven days a week except for weekdays-only Line 401, the Downtown Circulator. CAT has also been rapidly expanding service. Many lines are receiving significant service increases at every schedule change. The buses may be a bit dusty on the outside, but inside are clean and graffitti free. Best of all, the frequent rider discounts are terrific.
