A little rain didn't keep me from taking the opportunity on the way to the airport to rail fan the Santa Fe Junction in Kansas City. This junction can see up to 150 Trains per day - in a short period I saw at least 15 trains come through. This area is one of the best areas to view trains I've seen to date ... almost replicating a model railroad in the number of trains. It includes a fly over where you can watch 3 levels of trains.
