Tweaked Rosslyn station on Metro 2030 map

Jim Hamre of WMATA pointed out that Metro's current thinking on the separate Blue Line is that it would have to run one block west of the current Rosslyn station, to a new set of platforms connected by an underground walkway. I had hoped that the new tracks could pass right next to the old ones enabling a cross-platform transfer (after all, Rosslyn already has the two tracks on separate levels), but it appears this is not the case. I've updated the Metro 2030 map to reflect this station configuration.

I imagine the costs of doing it this way would probably be a little cheaper.

Yeah, I tried to conceptualize how they would add two more tracks and platforms to the current Rosslyn station, but it's tough to envision, especially when you consider the connections to and from existing track.

I'm also very curious about the possibility of triple tracking the whole new Blue line. In that case, it might make sense to route the Silver line with the Blue to Union Station.

David,

I took the liberty of taking your tweaked metrorail 2030 map and drawing in the form of a track schematic.

John
The track schematic 2030 is great!
You guys are working out all the kinks in this design.
I have one that needs to be looked at.
The Blue is a 1/2 service because it shares tracks with the yellow in VA. From Largo the demand is not that high yet - but we need to build in strategically placed center turnback tracks, one; at River Terrace so that Blue line trains that would be short turned would not have to "cross the plant" (cross the Orange, Silver lines). I don't know what the answer here is.
The last time I was there it seems that there might be some room just before Minnesota to build a 3rd track, so the Silver trains would turn there.
Then change the position of the Blue to be in the middle.
Also south of Rossyln just after the portal towards the Arlington Station there needs to be a middle track as well.
This is in the event that we need to run more service in the core and we need the ability to turn trains back.
This new service is going to fill up with Green/Yellow riders and help Union Station tremendously and there may be a need to have more service in the peak that can be turned back - making full use of the facility but not conflicting with the Yellow.
