Frequency of each condition that caused the engine to restart (exit from Battery Mode)
Compare exit reason distributions across locomotives
Compare stationary, moving, battery, and shutdown time across locomotives
Percentage of operational time spent on battery power: battery time / (battery time + engine on time).
Compare battery efficiency across locomotives. Sorted by efficiency (battery time / engine on time).
Frequency of each NOT OK condition across all near-miss shutdowns
Detailed breakdown showing stationary vs. moving time (based on GPS speed), plus battery and shutdown modes
Shows when the locomotive is moving (GPS speed > 0). Hold Ctrl (or Cmd) and use mouse wheel to zoom, click and drag to pan.
Visual timeline showing AESS mode changes over time. Hold Ctrl (or Cmd) and use mouse wheel to zoom, click and drag to pan.
Sessions are defined as transitions into Battery Mode and then transitions to any other mode. Total Sessions: 0

Cases where the locomotive was in AESS Mode 1 (RUN) and the idle timer counted down below 3 minutes, but was reset by a NOT OK condition before entering Mode 2. When TH (Throttle) or DIR (Direction) causes the reset but the locomotive does NOT move within 5 minutes, this may indicate operator gaming to defeat the system.
Total Near Misses: 0 | Likely Operator Gaming: 0
