DCMP 02 10 2013

The feeler car has made two passes over the branch, the first being during the first full week in December of 2012, the second pass was made during the first full week of February of 2013. It was parked on inbound track N1 west of the Haycock Road overpass when I was out there on 04 10 2013.

The third rail was energized for the first time from the junction to the east abutment at Old Chain Bridge Road the end of December of 2012. The cables connecting the traction power substation to the third rail in the interlocking west of the Spring Hill station have not been fully installed. Everything to the east appears to be done. The cables connecting the Wolf Trap traction power substation to the third rail are in place however the ground return cables have not been connected to the running rail return bond. Something else that I noticed that is different. There are 6 feeder cables connecting the substations to the third rail with 2 spare conduits. The setup in the existing system is 5 feeder cables and 2 spare conduits. Everything to the west appears to be done. It appears that Virginia Power has installed 2 new power line through Tysons Corner for exclusive use by WMATA. I noticed several manhole covers in the eastbound traffic lanes of Leesburg Pike VA-7 that have M Metro logos and an electric label on them. The manhole covers are the same diameter as WMATA's traction power manhole covers and Virginia Power's manhole covers.

Track has been laid from the Falls Church Yard lead junction to west of the tunnel portal.

Ground work for the second shop building in Falls Church yard is still underway as is the ground work for the box to be built around the loop.

The emergency trip station are online from the junction to the Anderson Road interlocking and from just west of Beulah Road to tail tracks west of the Wiehle-Reston East station. The electricians are still pulling cables and installing track side devices along the right of way between Beulah Road and the Tysons Corner station. Still don't know what the orange light on the boxes adjacent to emergency trip station are for.

All of the pedestrian bridge spans at all five stations over traffic lanes have been set. Only two spans remain to be set, the short span between the column and the entrance pavilion on the south side of Chain Bridge Road VA-123 at the Tysons Corner station. The other is the northern most span at the Wiehle-Reston East station that will connect the station to the Reston Station development that is still under construction.

All of the structural work for the platform and mezzanine canopies are done. The weather proofing sheet metal is still being installed at the Tysons Corner station.

All of the structural work for the entrance pavilion is done, escalators and elevator installation is well under way and in some places is complete. The structural work for the entrance pavilion canopies are at various stages of completion depending on location. McLean being the most complete Spring Hill road being the least complete. At this point it is hard to tell how the entrance pavilions will be secured when the system is closed at night.

The Kiss and Ride lot at the McLean station has curbs and gutters and has been paved, the final lift of asphalt and the sidewalks is all that remains to be done. The bus bays directly in the front of the station are partially compete. Platform pavers have been delivered to the McLean station. For those interested in procuring some for you patio I took a picture of the shipping label with the manufactures name on it (see below).

Tracks 17 and 18 in Greenbelt yard have been removed to make room for the Commissioning Facility shop building. Work is under way on the grade crossing south of the Greenbelt station the contractor will use to access the test track right of way. Grading for the test has has not begun.
