This covers a pretty broad area in super detail. It is 156 pages of awesome! it includes sidings, maps, how long it takes, etc. etc. its pretty much everything you wanted to know about the southern Michigan to Cincinnati area. Covers (east to west) the frontier yard in New York to east st Louis, MO/ILL. It has some of the Chicago, Detroit, Toledo, Louisville, and Pittsburgh but these are not main focus for this timetable. if your traveling St. Louis to NY the is the timetable to get for sure. It could be useful for lines out of Michigan. Definitely worth a read no matter what as its what the engineers are probably using to navigate.
