A route Metro Center - Shady Grove Road
B route Metro Center - Glenmont
C route Metro Center - Huntington
D route Metro Center - New Carrollton
E route Gallery Place - Greenbelt
F route Gallery Place - Branch Avenue
G route D and G Junction - Largo Town Center)
J route C and J Junction - Franconia-Springfield
K route Rosslyn / C and J Junction - Vienna
L route L'Enfant Plaza / F and L Junction - C and L junction / Pentagon
N route K and N Junction* - Ryan Road Ashburn (VA-277) (Future Tysons, Dulles, Loudoun County branch.)

The crossing point of the two train hall vaults in Metro Center is the zero chaining point for the A, B, C, D G, J and K routes.

The crossing point of the two train hall vaults in Gallery Place is the zero chaining point for the E, F and L routes.

The zero chaining point for the N route is at chaining station 236+26.00 (26,626.00' (8115.6m) east of zero chaining point in Metro Center) on the D route. Chaining station 236+26.00 is 196' (59.74m) east of the portal east of the Stadium-Armory station.

* The location of the future K and N junction is 2,294' (699.21m) west of the center of the West Fall Church station platform, geographically it under the Great Falls Street overpass. Great Falls Street is the third overpass east of the West Fall Church station.

Why there is no H Route.
The present section of the J route south of the Capitol Beltway (changed in the 1975 ARS) to Franconia-Springfield was previously designated H route (1968 ARS). The route that was never build west of Van Dorn Street Station to the then planed Backlick Road station (1968 ARS) was originally designated J route.

Why there is no I Route.
I is not used because the letter I (eye) closely resemble the numeral 1 (one).

Why there is no M Route.
The M route was/is to be assigned to the Colombia Pike Lincolnia branch off the C route south of Pentagon station.

Ahh, thanks for the great info, that's a lot of route alignments to cover, it's more like NYC Subway, I wonder if they had used those letters in public mode, that would be interesting.

The letter labels were created for civil engineering purposes and to create a simple letter number labeling system for the train control and signaling system. The line side relay sheds (train control room) are identified with a letter number labels as oppose to names.

Technically speaking the letter number labels are assigned to the RTU (Remote Terminal Unit) in the train control room. The physical RTU is the is the data link interface between the line side train control room and the train control system communication network. (aka IP or MAC address)

The station numbers are assigned in ascending order as the route radiates away from the geographic center of the system. (Chaining point zero) Each of these numbers identifies the station and the adjoining 'zone' of track that the local wayside train control room controls. The 4 two level transfer stations where the lines cross a 90 degrees (Metro Center, Gallery Place, L'Enfant Plaza and Fort Totten) have 2 letter number codes assigned to them one for each route that passes through the station. Some train control rooms do not have passenger station within their control 'zone'.

Number descending from 99 are assigned to yards, yard leads and junctions that are not within the control area of an adjacent passenger station way side train control room.

* Train control RTU that do not have a passenger station within their area of control.
** Train control RTUs that are physically along the J route but were built as part of the C route.

The reason why there is no list for the L route is because train control on the L route is under the control of the train control rooms in C07 Pentagon and F03 L'Enfant Plaza.

Atlanta MARTA, Bart, Baltimore Metro, Los Angeles MTA Red Line and Miami-Dade County Metrorail used uses similar schemes for civil engineering and train control room labeling.

Thanks for that nice info! I didn't know they got all that stuff.

Thanks for that nice info! I didn't know they got all that stuff.

That's just the schema as to how things are labeled.

There are RTUs in locations where there are no train control rooms.

The RTUs also are used to convey the status of support facilities throughout system to central control controllers.
Those status are;
Elevators (on off, level location, doors)
Escalators (on off, direction)
Ejector pumping stations
Fan Shafts (dampers, fan air flow direction)
Fare collection system data
Intrusion (doors, hatches, selected sections of right of way fence)
Smoke detection
Station air conditioning (chiller pumps, air handler fans, fresh air intake dampers and fans)
Station power (lighting, air conditioning, escalators, elevators. . .)
Station and tunnel backup power systems
Traction power substations
Traction power tie breaker stations (3 tie breaker station have their own RTUs; A98, J97, J98)
Vent shafts (dampers)

The data for the Passenger Information Messaging System (PIMS) is delivered to the equipment that drives those displays through the RTUs.

The communication network uses fiber optic as the communication media.

The fiber optic network also carries voice (telephone), radio (police, fire and trains frequencies) intranet (WMATA internal computer network), video (video from some of the surveillance cameras can be displayed on monitors in central control).

I am not sure but I believe Verzion uses some of the bandwidth on WMATA fiber optic network for their cellular phone system. Verzion does have fiber optic cables in some of the tunnels that is totally separate from WMATA's fiber optic network.

Wow, that's amazing, even with CCTV, intranet/internet and the brain, literally of the entire system. And:

I think you meant to put the N instead of M in the numeral system, such as N99, N14 etc...

. . . . . . .

You are correct. Corrected above.

The above list was ripped from an older document I created based on the information from the Draft Environmental Impact Statement (DEIS) and other sources. At the time of the publishing of the DEIS I had not received confirmation that the Tyson, Dulles, Loudoun County branch was in fact the N route. Previously I was unofficially calling it the M route.

I saw the corrections. Thanks

Oh I see, it sure was a very old document before the update

Your welcome

The document I created and used as reference is dated May 13, 2005, The DEIS dates to October 07, 2002.

None of the FEIS documents were published on the web. The only thing that was published on the web was the Executive Summary. To see all of the Volumes of the DEIS one had to go to one of the Public Libraries or one of the Government Office in Fairfax or Loudoun County Virginia, which I did several time to make photo copies of selected pages.

Conformation that the Tysons, Dulles, Loudoun County branch is in fact the N Route was confirmed in the FEIS document Volume IV: General Construction Site Plan (1.48 MB PDF) on sheet 005, The PDF document is dated December 10, 2004, the date on the pages of the document are July 2004. I didn’t notice the N label on the map on sheet 005 until after I created the document I used as a reference.

You probably have seen these, If not here they are again.

WMATA metrorail 129 mile ARS track schematic The system today plus 23 mile Tysons, Dulles, Loudoun County N Route.
(Note: The schematic is basically the same as what is in the present plans. The only major difference is the future provision for a station at Wolf Trap has been deleted. Minor differences are station names.)
