Anomaly detection — daily A2F SPC rules
Delay attribution — DAPR cause-code breakdown
Forecasting — prediction intervals and possession-exposure estimates

The Great Eastern Main Line carries every rail freight movement between Felixstowe — Britain’s largest container port — and the national network, via Ipswich, Colchester, and Stratford. It is the most intermodal-intensive corridor on the British freight network.

Three to four freight operators run regular services across the corridor; GB Railfreight and Freightliner Intermodal carry the largest shares.
