I just wanted to revisit this. That RVL trains running between Hunter and Aldene can and do use both tracks. There is no designated direction, both Tracks 1 and 2 are bi-directional. Freight usually moves on Track 2 and passenger trains on Track 1...but not always.
This afternoon Train 5448 to Newark was scheduled to stop at Roselle Park on Track 1 at 6:17 PM. Train 5441 to Raritan was scheduled to stop at Roselle Park at 6:18 PM on Track 2.
- I wanted to edit my post to include a link to an NJ Transit page for the Roselle Park station. It has a "departure vision" feature so you can see what track the various NJ Transit trains will be operating on at Roselle Park. Use this link
and click on View DepartureVision
at the top of the page.
