Unfortunately my phone bricked two days after the event, taking about half the trip photos with it including most of the underground material. Fortunately I had enough regular camera content to put together a reasonable post.
Starting off at Market East, the outbound R1 Airport took me on what turned out to be my last run through SEPTA's ARSENAL interlocking in its post-NECIP configuration before passing northbound Amtrak Silver Meteor Train 98 led by ACS-68 #650 at PHIL.
Our R1 train had a student engineer on board who was having some issues with the overly sensitive PTC system that continued to hinder performance. I was able to catch a little of the system in operation returning from the Airport, but refer to my related signaling blog post for a more in-depth analysis.
Eastwick was built as an infill station on the R1 Airport in 1997 and allows for a walking connection to the Route 36 trolley's western terminus. Currently mid-day R1 trains send to pass here as we can see with out inbound train with Silverliner V #706 and an outbound train with Silverliner V #869. Regrettably #869 is not lettered "PENNSYLVANIA".
The walk to the Eastwick Loop down Mario Lanza Blvd took us by a feral cat colony that is probably causing a lot of ecological harm.
Arriving at the Eastwick we found K-car trolleys #9074 and #9001, with #9048 soon arriving, but since one apparently can't board at the loop we messed a headway herding the entire group over to the passenger shelter.
We used the headway time to take a group photo of the morning trip attendees before #9019 showed up, passed #9001 and #9048 on the inside loop then ran light back to Elmwood depot leaving us to ultimately depart on #9001.
