Correct. The tracks currently sharing the I84 viaduct footprint are scheduled to be moved first in the late 2020s.
CDOT will hopefully also complete the remaining Hartford Line projects by the late 2020s:
1. New additional stations in Hamden, Newington, West Hartford and Enfield.
2. New replacement stations in Windsor and Windsor Locks.
3. Second track between Windsor Locks and Enfield
4. Refurbishment/replacement of the Connecticut River bridge (technically not part of the Hartford Line project but ideal for full schedule between Hartford and Springfield).
