What equipment is used through Lake Forest?

I will be traveling to the Chicago area this weekend and staying up in Lake Forest. What sort of equipment is used on the Milwaukee District/North Line and the Union Pacific/North Line? I am not sure which Lake Forest station we will use, but I was just curious to know what I would be riding on when traveling into the city on Saturday.

More of the newer equipment (6000 series) can be found on the UP line through Lake Forest, though all are used as trailers. A lot of the older Budd cars in the 7200/8200 series can be found on the Milwaukee side; the newer cars can be found here as well, but they're mainly confined to the cab cars in the 8500 series. If you're looking for any of the reacquired Pullman coaches, UP is your best bet...
