Lots of benefits for us locals including eliminating all those car rental shuttles and congestion, in addition to the Metra connection. When leaving my office in the Loop during rush hour, the Metra is my preferred method to get to ORD. Environmentally friendlier, I'm sure.

The ATS will get significantly busier. It is usually full particularly in the afternoon and early evening with folks transiting between T1, T2, T3 and T5. With several thousand additional riders per day for rental, they are going to have to substantially increase service and number of cars to keep up with the demand.
