String-line diagram of every MBTA subway train on Monday, August 24, 2026

Time runs left to right across the service day (4 AM → 3 AM). Each panel is one line, top to bottom along the route. Every diagonal is a single train: steep is fast, flat is stopped, a cluster is bunching, and blank space is the wait you remember.
