Not saying there can't be improvements (hey, run all the Joliet trains via the main line and run separate Beverly branch trains at all times, I got no problem with that), but there's no capacity problem at LaSalle St. Station and there won't be even when and if the Southwest Service trains are routed there, but there is a capacity problem at Randolph Street (only five tracks with lots of arrivals and departures) with the current Metra Electric service. Getting the Beverly DMU'S or EMU's from the Rock to the Electric District could be done via the St. Charles Air Line, but would unnecessarily lengthen the trip (LaSalle Street would be in sight as the trains turn east and then north. Unless you want to start the trains in Brainard, run south along the Beverly branch and then hook up with the Electric near Vermont St. in Blue Island, which of course would have the train running in the wrong direction for a big portion of the trip.
