Names of main lines

What are the names of the main lines that CSX uses? I guess 'main' would be defined by traffic, or maybe by joining other lines.
I know about the A and S lines (http://en.wikipedia.org/wiki/Image:CSX_ ... _lines.png), though large parts of the S line are no longer used.
Is the Water Level Route still called that?
What other major named lines exist?

The Water Level Route is still referred to as that, but it's sort of split up into segments.

For example, from Buffalo, NY to Syracuse, it's called the "Rochester Subdivision". From Syracuse to Selkirk, it's "Mohawk Subdivision". Conrail's "Montreal Secondary" is now the "St. Lawrence Subdivision".

Maybe others can help fill in with some more?

Selkirk to CP92 in Wilbraham, Mass was the Berkshire Line on Conrail, now it is the Berkshire (BK) Sub-Division.

CP-92 to Boston (where it end @ Amtrak's CP Cove) was the Boston Line, but is now the Boston (BO) Sub-division.

Actually I have a list of the subdivisions. I know the A and S lines are still called that (Orlando MPO documents call them that), even though they also have SD names (Sanford, Lakeland, etc).
If there are no "official" names, which routes carry large amounts of traffic?

The link gives an idea on traffic amounts from various sources.

When CSX took over the "Water Level Route" and associated lines in NY State and New England from Conrail they applied the name "Albany Service Lane" for these operations.

CSX's Riverline runs from CP1 in North Bergen, New Jersey to CP-SK up in Selkirk. It sees a good amount of trains maybe 30-40 trains daily. Down in North Bergen the Northern Branch splits off at CP3 and goes up a little bit just blocks away from the Riverline. I dont know exactly how far up it goes but last months Railpace had an article featuring it.

Actually the "River Line" is now broken up into two subdivisions. Between CP-1 and CP-7 is the Bergen Sub. From CP-7 to CP SK is the River Sub.
