The direction indicator is the only clue as to if you need to reduce to 60 or stay at 80. Just another wonderful signaling hack by MNRR brought on by the decision to cheap out on interlocking signals.The maximum authorized speed through CP112 interlocking (what you call "Woodlawn") is 60 MPH. No need to rely on the route indicators to know how fast you can go; the timetable spells it out. If you're qualified on the timetable and physical characteristics, you know this.
You can call it a "hack", but it's a failsafe system, just as the previous ABS/TCS was failsafe. The engineer's compliance with the timetable and operating rules is assumed and required.
