Good start, but centering the column headers ("Rail Line/Location" and "Date/Train Number") over wide columns while left-justifying the data below is visually confusing. I would either center everything, left-justify everything, or make the columns narrower, a la RailPictures.net. And if I may nitpick just a little more, "SouthWest Service" has a capital W according to Metra. Sorry, the copy editor in me can't ignore things like that.
Nice work, though, on the entire site. I know what a huge undertaking it is to assemble a site like that, and you've put together a well-done product.
