Methodology & sources

All figures derive from Network Rail's NROD TRUST feed, processed via the Gauge Intelligence ingest pipeline. Period definitions, A2F (Arrival to Fifteen), the Wilson 90% interval, daily anomaly rules, cross-view reconciliation, and delay attribution are documented at:

Data window — period boundaries and the data-as-of cutoff
League tables — cross-view reconciliation across the four analytical views
Anomaly detection — daily A2F SPC rules
Delay attribution — DAPR cause-code breakdown
Forecasting — prediction intervals and possession-exposure estimates

Bristol and Avonmouth are the Bristol Port Company’s facilities on the Severn estuary — Avonmouth Docks on the north bank and Royal Portbury Docks on the south. Rail-freight terminating points at Avonmouth are confirmed against BPLAN; the published register entry is held pending a full closed rail period of clean TRUST data covering the port’s terminating TIPLOCs.

Four derivations are released to commercial-licence subscribers rather than the public archive. Each one reconciles TRUST source-data against Network Rail's Historic Delay Attribution record independently, not republished from public statistics.
