I suspect the reason for GCT's earlier track postings is that there are many more
available tracks than at Penn (remember - Grand Central is a terminal, not a through
station). In my experience, trains usually do arrive and leave from the same tracks
each day, at least the Harlem division trains do.
Metro North has a lot more tracks to work with, which gives it much
greater flexibility in committing trains to tracks early. The LIRR
and NJT, on the other, share (along with Amtrak) a much smaller
terminal (in terms of track capacity) depsite the fact that the LIRR
alone is bigger than MN, and NJT only adds to it. As a result,
the LIRR and NJT can't post tracks too far in advance 'cause odds
are there's another train already boarding there. Despite the tight
scheduling the LIRR (don't know about NJT) does manage to _typically_
keep departures on the same tracks day after day, though it's
certainly not guaranteed.

But compared to stations in Europe and Japan, both stations are
inefficiently used. You could handle the traffic with far fewer
tracks.

Actually, GCT has a couple of loop tracks. In addition, the main service facilities
aren't in the Bronx, but farther out on the lines. The main one is at Croton-Harmon on
the Hudson line.
