Sure enough, with only about two weeks being on the property, SEPTA is already putting advertisements on the new hybrids. They now have side and rear ads. A few of them even have banner ads along the roof line, including 8129.
Also of note, with the new hybrids coming in, Callowhill is sending some of their original 50xx Ikaruses to Midvale. Several of them in no particular order have been spotted on Midvale routes, including 5025 and 5031. 5030 was spotted at Comly a few days ago as well. Also of note 5552, 5555, 5556, and 5557 are now at Midvale. 5552 and 5556 were on the 32 yesterday while 5557 was on the 9 and 5555 was on the 56. Expect things to go a little crazy in terms of bus assignments while the new hybrids are coming in.
