Metric Reminder
This dashboard intentionally penalizes late departures out of Penn Station, but it does not depend on each train’s
scheduled NYP→HUD running time. In other words, it captures the lived end-to-end experience from the rider’s NYP departure
slot to realized HUD departure.
Run-by-Run Trend
Y-axis shows total minutes from scheduled NYP departure to actual HUD departure on a compressed log-like scale, so rare blowups stay visible without flattening the typical runs. X-axis runs across the study window.
EWMA Trend By Train
Smoothed with a 5-weekday half-life. Inputs are clipped at 180 minutes so rare blowups do not overwhelm the trend.
