Philly Area Interlocking Updates

 I have two items of interest from the Philly area.  First, new signal masts are up at SEPTA's ARSENAL interlocking covering the new crossover and turnback south of the University City station.  While not directly replacing the LED PRR position lights on the signal bridge at ARSENAL proper, the masts are arranged for the reduced aspect Rule 562 signals despite both the Airport Line and West Chester Line being outfitted for Rule 261 with waysides.  I'm still not 100% sure what the final configuration will be, but it doesn't look good :-(

In other news a recent photo from PAOLI shows substantial modifications to the 4-track full crossover that was made largely redundant by the conversion of the Paoli Station from side platforms to a central island. It also appears that the west end pneumatic point machines have been converted to electric. Here is a diagram of what remains.
