Interpretation Guide
Sessions are defined as transitions into Energy Module and then transitions to any other mode. Total Sessions: 0 Likely Override: 0

Cases where the locomotive was engine on and idle and the idle timer counted down below 3 minutes, but was reset by a NOT OK condition before entering Energy Module. When TH (Throttle) or DIR (Direction) causes the reset but the locomotive does NOT move within 5 minutes, this may indicate operator override to defeat the system.
Total Near Misses: 0 Likely Override: 0
| # | Timestamp | Idle Timer | Min to Shutdown | NOT OK Fields | Override? | Data |

Periods when the locomotive is actively doing work (Engine Running) + In Gear + Throttle Applied (MU NOTCH > 0). Sessions end when entering Energy Module, Operator Shutdown, Disconnect, or 30+ minutes without working activity.
