Leaving Philly the 1990's era Conrail signals at CP-PARK, CP-BELMONT, CP-RIVER and CP-FALLS are all still in place, but the Reading brackets next to I-76 have been replaced and CP-ROCK has been re-signaled along with some of the ABS signals between there CP-NORRIS.

One major issue with Rule 251 operation emerged when needing to run under a Form D from CP-TITUS to CP-PHOENIX our train was forced to run at Restricted speed for 4 miles because the reverse direction signal only supported Stop and Restricting and with no exit signal we had to travel through the very long CP-PHOENIX and then the block beyond it under a Restricting indication.

The Reading downtown WYE retains all its Conrail updated Reading signaling including CP-CENTER. Also the line between there and CP-WYOMISSING JCT is still operated under Rule 251.
The Harrisburg Line between Reading and Harrisburg was one of NS's first major re-signaling projects right after the Conrail merger and involved replacement of the Rule 251 system with full CTC and crossovers due to the 50+ trains a day that the line sees. This uses the short-lived NS standard of non-Darth traffic light signals and the special "crankable" signal masts where the heads could be lowered via cable for maintenance. That practice did not catch on and has since been abandoned. The old CP-TARA retains its original Conrail signals, with everything else being NS Vintage. At Harrisburg the Reading vintage CAPITOL tower remains standing.
There is a bit of news at the Rockville Bridge wye in that aside from the new Darth Vader mast for the yard lead exit at CP-ROCKVILLE, the pneumatic switches at CP-WYE have recently been converted to electric, I suspect along with CP-HIP across the river.
