This is Friendship Heights looking East. The double main line of the HP&H is at the left edge passing between the old and new sections of Karen's Cookie Factory.  The buildings are joined over the tracks by a crossover room.  The track in Friendship Heights includes a WYE.  This allows engines and cars to be turned. A Wye is a place on the railroad for a three point turn.   One leg goes from the lower left corner around the curve along side Karen's Cookie Factory.  Then it crosses the scene to a point behind the green building in the right corner. It then goes back down to the lower left corner to complete the three points.   There are several close of views of this section that can been seen from the Friendship Heights West page.
