I think the issue is that to bring the new line to the same grade as the existing terminal would have required some other exceedingly expensive tunnel so the trains could wind their way up to the correct elevation. This is the same reason that the F train, which uses the same tunnel, has such deep stations under midtown east

To your point, how does the F train eventually end up at the 57 street station? I checked the depth and the 63rd street station is 155 feet deep but the 57 street stop is only 30.

How can the subway do it but not the LIRR? I’m sure there is a good answer someplace but genuinely curious.
