Posted by Sand Box John on Sat Jun 30 15:28:01 2012 The double crossover east of the junction will be a separate interlocking, meaning there are signals protecting the west entrance of the double crossover east of the junction and signals protecting the facing points of the Junction west of the double crossover. The layout is basically the same as L'Enfant Plaza, only difference being there is only 1 track circuit between double crossover and junction on each track track, L'Enfant Plaza has 3.The Falls Church yard lead tunnel is done. Contractor was back filling the excavation. The entrance pavilions are starting to come up out of the ground, Tysons McLean being furthest along. None of the architectural precast concrete facade panels have been installed at the Greensboro station. The contractor has not begun assembling the arched mezzanine / platform canopies at any of the stations in Tysons Corner. Short platforms at both ends of the Spring Hill station cantilever past the columns that support the ends of the station platform to reach the backsides of the emergence exit stair structure. Rail has been pulled west to the Spring Hill station on outbound track N2, just short of the station on inbound track N1. Lifting gantry #2 is presently working in the Median of the Dulles Access Road. Only 4 spans are left to be built east to the west abutment. Rail is staged in median of the Dulles Access Road to about a 1/4 west of the abutment. Inbound track N1 has been laid from the west end Wiehle Avenue Pocket to a point east of Trap Road, outbound track N2 has been laid from point roughly 1/4 east of the Wiehle Avenue overpass a point east of Trap Road. All of the traction power substation and train control rooms along the Dulles Access road are in place. The signaling and train control contractor was working in the area of the junction when I visited the area.
