Capping A: Unlocks A-E, and the A-B shortcut/route
Capping B: Unlocks B-C, extends safety bridges below E
Capping C: Starts the one-way train to D, extends bridges to reach E
Capping D: Locks down Red's quick access to E, flips guardrails up, and opens train gates at B to make Blu's trip faster
Capping all points pulls E upwards slowly
