|Westbound signals at CP-CONPIT with the original Rule 280b 'C' lamps installed.|
|Same cab signals, just different packaging.|
As you can see the new 'C' equipped mast will lack the third head included on the existing mast as Medium Approach Medium is not considered necessary where a cab signal can be held at Approach Medium after a train diverges over Medium Clear. This is one of the few circumstances where a PTC related re-signaling project has actually brought about more interesting signaling.
While I was not able to stop by CP-ETNA to see if the Rule 562 operation stopped there or would continue to CP-PENN, I suspect it will stop at ETNA, at least until the Conway Corridor is fully re-signaled.
