Unfortunately, the Shore Line continues west of New Haven to NYC.100x yes! I frankly believe the Shore Line won't be able to be used reliably in 10-20 years due to climate change and sea level rise.
For this reason I want to see the Upper Harlem Line restored; both the New Haven and Hudson lines are very flood-prone with sea level rise. The Harlem Line is not (it's at high elevations the whole way and the tendency to river flooding can be fixed with minor work), so it'll be the reliable route out of NYC to the north. Nobody's been thinking about this though. :-(
