They're scheduled trips. Although from what I've heard the morning Heath Street trip is staffed by Part-Timers, and the evening trip has 2 scheduled operators and an OT list position (often filled by an operator who does WAY too much overtime).
Also the evening Lechmere trip alternates between the 6:28pm trip and the one before (wanna say 6:20pm?)
