It's been a while sense I published one of these, so let get on with it.
I will first start out with the one I forgot to post in August followed by the one from last week.
Dulles Corridor Metrorail Project Pictures 09 18 2018
All of the stations are well beyond being structurally complete. Several of the stations have had their granite edge and platform pavers installed. All of the the pedestrian bridges have been placed and are at various stages of having floors and ceiling installed. Innovation Center and Herndon are the closest to being totally done followed by Reston Town Center, Dulles Airport, Loudoun Gateway and Ashburn.
Entrance pavilion at all of the station are structurally complete and have their precast panels in place. Some have escalator and or elevators in place at various stages of completion. The last one to go up was Herndon north, go figure, it still has a some precast panels that still need to be installed. I noticed a lonely pedestrian bridge segment sitting on the ground near traction power substation #13 at Herndon. Seem there was a late change order made, that pedestrian bridge segment will connect the Herndon south entrance pavilion to level 2 of the existing garage.
At Dulles Airport, roughly 85 percent of the glazing between the mezzanine and station platform has been installed. The canopy is mostly complete. The precast panels on the station will not have the brick veneer like the other stations. The 4 mezzanine to platform elevators will be traction as apposed to hydraulic as use at the other stations and entrance pavilions. Something that was not spotted by me early on is there will be a traction power tie breaker on the east end of the station platform. All of the traction power substation and tie breakers on the airport property will not have precast concrete panels with brick veneer like the others, but will have vertical corrugated gray medal siding like what is used on the various airport service building.
The second new garage at Herndon is structurally complete, there will be no garages at Reston Town Center. A garage is near completion at Innovation Center south. The garage at Loudoun Gateway is roughly half done. A garage at Ashburn north is done and is open now to free parking.
Little to none of the of the sidewalks, access roadways to the garages, kiss and ride and bus terminals has been done at most of the stations. The exceptions being Innovation Center south and Ashburn south, both of those station have their bus terminal roadways in place. An aside note, the last 2 lane segment of Sunrise Valley Drive is being widened to 4 lanes just west of Innovation Center.
Track laying is mostly complete, only few short segments east of Ashburn need to be done. All of the interlocking track work is done. Third rail has been completed to the west yard lead junction and is proceeding to the west. It’s going to be a roller coaster ride through the west yard lead junction on the mainline.
Electricians have begun work wiring up signaling and training control as far west as the yard lead junctions. Signal heads have been installed at the interlocking was far west as the double crossover along Autopilot Drive. Fence intrusion detection is at various stages of completion east of the airport. The traction power cable management on the airport elevateds appears to be more compact then what was installed in Tysons Corner.
Traction power substations are mostly done with some still remaining to have their transformers installed along with their enclosures. The transformers are being sourced from a manufacture in Roanoke Virginia.
The buildings at Dulles Yard are structurally complete and like the airport station do not have brick veneer on them. Track work is mostly done and the electricians have begun work wiring up signaling system. Third rail has been installed in the storage tracks and along most of the length of the leads. Access roads in the yard are at various levels of completion.
The VA-606 widening project from 2 lanes to 4 south of the Dulles Greenway in front yard was completed and opened late last year.

Dulles Corridor Metrorail Project Pictures 12 09 2018
All of the stations are essentially done, platform tile, granite edge, stairs. Escalators and elevators in the stations and entrance pavilions are in various stages of completion. Unable to verify the completion of the floor finish on the mezzanines and pedestrian bridges of the stations with the exception of the Dulles Airport. Floor tile is yet to be set on that station mezzanine.
All of the trackage is complete. The installation of the wayside train control and signaling hardware is well underway. It's far along to the point that the signals in the Innovation Center interlocking and in the Horsepen Run and Autopilot Drive interlockings on either side of the airport station are displaying red aspects. Installation of the wayside train control and signaling hardware west of the west yard lead is less far along. The 35KV power supply bus has been energized, most if not all of the passenger stations are drawing power from that distribution system. All of the traction power substation and tiebreakers are for all practical purposes complete. Third rail cable connections are done to the west end of the west yard leads.
Reston Town Center north entrance pavilion has its glazing in place and the sheet medal roofs installed. Grading for the bus terminal roadway and walkways has not been done. It appears that a contract has been let, presumably by others, to construct a pedestrian bridge that will cross from the entrance pavilion to north side of Sunset Hill Road. South entrance pavilion has yet to have its glazing placed and the sheet medal roofs installed. Grading partially complete for the bus terminal roadway and walkways adjacent to the entrance pavilion.
Herndon north entrance pavilion has yet to have its glazing placed and the sheet medal roofs installed. No grading has been done for the walkways the will access the entrance from Herndon Parkway. South entrance pavilion has some of glazing in place and the sheet medal roofs at yet to be installed. The elevator and stair structure that will directly connect the existing garage entrance pavilion only lacks the roof panel and the pedestrian bridge between has not been set.
Innovation Center north lacks its sheet medal roof on the entrance canopy at the opening the grade level pedestrian bridge. The bus terminal roadway is complete. Some of the walkways have been place at the west end and grading is done for the remainder. South entrance pavilion has its sheet medal roof and some of the glazing is in place. The bus terminal roadway is in place as mentioned in previews post. Grading for the walkways adjacent to the entrance pavilion had not been done. The contractor building the garage has begun to correct the issues involving the premature settling of the columns by placing large spread footing at their base. Walkway have been placed along the new eastbound Sunrise Valley Road roadway that has not been opened to traffic.
Dulles Airport entrance security gate is in place in the now open garage 1 pedestrian tunnel. Opposite of the entrance is another security gate that the fare vendors will be located at. Glazing between the underside of the elevated and the walls surrounding the mezzanine have been placed. Grates that will control the convection are flow between top of the glazing and the underside of the elevated is partly complete. Shelters on the platform are partly complete. Station name signage along the parapet wall opposite the platform edges has been placed. The concrete walls enclosing the ancillary areas under the elevated and at platform level will be covered with vertical seamed sheet metal siding that is use on existing airport authority service and ancillary buildings on the airport property.
Loudoun Gateway lacks its sheet medal roof on the entrance pavilion and has yet to have its glazing placed. The garage is structurally complete. There has been no grading done for the station access roadways, bus terminal an walkways.
Ashburn both north and south entrance pavilions lacks their sheet medal roofs and no glazing has been placed. The mezzanine canopy also lacks its sheet medal roof. Grading has been done and curbs have been placed in the east half of the north bus terminal. Grading has been done and curbs have been placed in the station access roadway to halfway around the curve the west half of the bus terminal, As mentioned before the bus terminal at the south bus terminal is complete. No walkways are in place at either the north or south bus terminals or entrance pavilions.
Dulles Yard has all of the track work done. The signaling system installation is well under way. Most if not all of the roadways and parking lots are done. Installation of the security fence around the yard is mostly complete. Installation of the access gates and gate houses has not been done.
