Since the "North Yard" (which encompasses a car shed, roundhouse, turntable, coal storage, and a myriad of railroad tracks) doesn't appear to have its own work thread, and because the grading that's occurring is important to all these projects, here's pictures from the recent work that contractor Jeff Verney has done.
First photo is taken from the driveway of the house, looking easterly. The survey stake with the yellow tape may be one corner of the roundhouse.
Second photo is taken from the end of the spur, looking south.
Third photo is taken from near where the north wall of the car shed will be, looking northerly at the current end of the spur.
Last photo is taken from Track 7, looking westerly.
