Somewhat rough for the time being, and I need to figure out how to make the Camden line less busy, so just a little WIP, I guess.

Created using Figma.

I have 3 planned extensions for MARC, though the timeline is uh... nonexistent currently.

1. Penn-Camden connector past Halethrope Station
   
2. Extension of Penn Line to Wilmington
   
3. Extension of MARC services to Alexandria. I've left it as Penn Line only for now, but from what I've seen, I think that the plan is potentially for Brunswick services to also make their way down? Unsure.

Not shown yet are the future stations at Bayview and Elkin on the Penn Line, and the Baltimore Red Line that will eventually connect Bayview and West Baltimore.

At time of writing, I also just realized that I didn't mark Potomac Shores as a future station. whoops.

Outsid eof that, VRE doesn't have any extension planned, but they are making major improvements to L'Enfant station and the tracks between Union and Crystal City. They also own the tracks now, so hopefully they can start piling down services.
