"Blue Comet" and "Queen of the Valley" were the names of trains, not train lines. Whenever I want to know where a particular rail line goes (or where it went), I usually check out a map. Look what turned up when I typed in "Jersey Central Lines map" into Google image search:

Try that for your other question regarding "all the former rail companies in new jersey." If you're still having difficulty after your search, we'll try to help. If you really want to see all lines in New Jersey past and present, check out the SPV Atlas for the Northeast:
