- Schedules for Main Line--30th St Upper trains can be made out with no
- reference to schedules of Northeast Corridor--30th St Lower trains.
- Likewise, late running on one of the two routings would not cause any
- conflicting use of one track or block the other routing. This seems
- significant to me, that's all. It's not as if the Main and NEC merged
- at Zoo and then diverged again into the two 30th St approaches; rather
- the two 30th St approaches are distinct already as a train moves south
- out of the Zoo triangle.
-
- Of course the routings are not totally independent in at least two
- respects-- firstly, Zoo is a single interlocking, and secondly, many
- other trains run a routing Northeast Corridor--30th St Upper.
- Compare, though, a case where any two rail lines cross and there are
- some trains running from one line into the other-- there too you would
- have a single interlocking and some interdependence of scheduling.
- Zoo is of course a LOT more complex than that.
-
- There is good reason to say all of Zoo is part of the corridor; there
- is also reason to distinguish the parts of Zoo between those tracks
- used by corridor train services and others. I see it both ways.
-
- How do you consider the freight High Line past 30th St? he asks
- fiendishly.

-
- This refers to the 5th and 6th track, right? I don't know of any
- places where there is any reason to say so.
