Dolton, Illinois, is where CSX & UP cross the Harbor Belt on Chicago's south side. Dolton, apart from being really ugly, has a lot of trains and an active tower. I was fortunate enough to be invited into the tower by towerman Ralph on two afternoons, which was really good, since I got some nice interior shots, and out of the rain. The train of the day is the bottle train, taking molten steel from one mill to another, in big insulated, I guess bottle cars. I saw power from UP, CSX, NS, CR, BNSF, CP, IHB, ST.L&H, WC, SOO, and a bunch of leasers. Since Ralph was nice enough to give me lineups, I was able to identify most trains.
