What do you mean John by "roller coaster ride"? Does the track curve a lot back and forth? Or are there elevation changes?


Two significant elevation changes over a distance of roughly a half mile in the area of the west yard lead junction. 35' drop, 20' climb followed by a 25' drop. The design in the preliminary engineering had most of the elevation change in west yard lead track YL2 as it flew over both mainline tracks and descended to the junction that was to be located in the 25' drop.

Sand Box John, may I ask what happened to your update blog? Also it appears that contact rail is being installed between the mainline crossover at the Dulles Greenway and 606 along the eastbound side.

I took it down for personal reasons and because Google kept making it more time consuming to markup the html code. Everything is archived on optical media and on a couple rack serves.

Also it appears that contact rail is being installed between the mainline crossover at the Dulles Greenway and 606 along the eastbound side.

When I was out there a couple of months ago there was evidence they were progressing west from the yard lead junction towards the Loudoun Gateway station.
