SJ, employee timetables are supposed to be guarded with our lives, especially in this day of increased security. I got one for somebody once, and there has been nothing but trouble since.
But, nothing says I can’t “read” a little bit to you–oh, yes–something about divulging information. Well, let me just describe it.
Each subdivision is shown in a table of its own. I know you’re a little familiar with UP’s Geneva Subdivision, since you rode it from Elburn to Chicago, and watched it roll in Rochelle and DeKalb.
So we have a page which lists all of the stations and control points, in order, including the code numbers ("Circ-7"s, for example), connected with each station, its milepost, and the distance between it and the adjacent station. It also shows which rules cover operation in a given territory (mostly CTC and ATC for this line) and how many main tracks there are. If there were sidings at any of the stations on the line, it would give their length in feet (the Geneva Sub has only one siding–in Nelson).
After this table, there are sections referring to special instructions for each subdivision:
1: Main track authority: basically states where CTC is in effect, and, where it isn’t, the direction of the current of traffic on each track for multiple main lines.
2: Maximum speed table: Looks a lot more complicated than it is. In most places on this sub, trains can go 70. But the devil is in the details.
3: Other speed restrictions: more details in which the devil can hide.
4: Main track designations: There may be more tracks in a given area than there are main tracks; this just tells you how many tracks are main tracks.
5: Milepost equations: In the event that mileposts are missing due to line relocations, or the numbers start over at a junction, or things like that. On the Geneva Sub, there is nothing like t
