Got myself an answer...
about the PTC question at Hall Interlocking on the LIRR: LIRR applied and received approval for, a mainline track exclusion addendum for the Jamaica complex of which this interlocking is a part. It's not the case that because it's an interlocking, "PTC won't help." It is the case that section of the railroad has been approved for an exemption from the PTC requirement.
Had to go all the way back to FRA's approval of the PTCIP in 2010 to find that one.
