A few more, got a few more blocks up in the distance. Added Sissons Stone Yard just east of the B&O tracks. Funny thing is, I'm not planning much more of the B&O and only a little more PRR, just enough to have meaningful interchange tracks with the M&Pa. Both the PRR and B&O will have portals which will spit out trains every now and then, just as some kinetic backdrop.
Shot from the North Ave bridge, a B&O freight makes it's way south toward the Howard Street tunnel

Sissons Stone Yard and spur, next to the B&O Belt line on the east side of the valley
I only know where it was, not what it looked like, so this is a TOTAL guess....
Bird's eye view of the valley, PRR GG1 and coaches in the foreground on PRR tracks, opposite back is the PRR interchange track with the M&pa; B&O curves at top left toward it's tunnel below 26th Street
