Presented for review: a MARC shuttle between Deanwood and New Carrolton Metros
I think it's a good idea, but it won't work in the short time frame. Here's what I commented there:
The first negative is that the line is going through the Virginia Avenue Tunnel, which if I remember is being reconstructed. That means the single track is unavailable for ANY traffic. Well, there goes going to L'Efant Plaza.
The second is that the line may not be rated for passenger service, and it may take some time (more than a year) just to get CSX and the Federal Railroad Administration to push the paperwork to get it rated... and have CSX pay the FRA to do it.
That said, strike up Wikimapia and lets take a look.
The interlockings (aka track switches) in question are CARROLL to the north of New Carrolton Metro/MARC/Amtrak, LANDOVER to the south of the station, DEANWOOD near the Deanwood Metro station, and Metro's D/G next to Minnesota Avenue Metro. Okay, it's logical to have Metrorail trains turn at Minnesota Avenue. (Note, it is custom to list interlockings in all caps)
But then things get bad/expensive.
New Carrolton has a third track (track 1) but it needs access. The only way is to build an entranceway to the existing tunnel and then the platform (assuming 2-4 train cars long). Oh, and the elevator too. Hell, you might as well just extend track A up from LANDOVER and build a proper long-term platform there.
Landover Metro itself requires tunnelling to get to the other side, and that doesn't include what the station layout actually is. Then you can get to the platform.
Cheverly is much easier, as it's on CSX rail. You just need the platform, ramp, et all on one side, although you could do both sides...
Deanwood isn't accessible to both sides. The north side can be built but that's it. But you won't get an interlocking and you're stuck with one track. The DEANWOOD interlocking is over on the access to the Camden Line.
Minnesota Avenue is also the same as Deanwood.
In fact, the only interlocking you have is all the way in Anacostia, past the rail yard, and it's called... ANACOSTIA.
So, for a shuttle train, you got a good amount of reconstruction that won't be done until well after the repairs are done to ALL the Metro lines. That's just a waste, and both the FRA and FTA isn't going to approve it. CSX, Amtrak, WMATA, and MARC isn't going to front the money for it because of it. (For an idea on how long it would take with all the paperwork, look up the latest effort to replace Baltimore's B&P Tunnel, as well as four-tracking around BWI Amtrak station; in short, *years*)
Nice idea. But it's not going to work.
