Grangemouth — Period 2 2026-27 (26 April – 23 May) report

Operators at Grangemouth-inbound

Freightliner Intermodal ran the most grangemouth-inbound services in Period 2 2026-27 (12 of 24 completed arrivals). The full per-operator reliability comparison is deferred while the v1.0 industry review edition corrections inbox remains open.

Publishing a per-operator on-time comparison for the busiest freight operators at a single destination before the launch-cohort corrections cycle closes would treat provisional attribution as settled. The table returns at v2.0 general availability. The league-table methodology documents the comparison framework; the release cadence page sets out the four exit criteria for v2.0.

Outbound destinations — services leaving Grangemouth

DIRFT Daventry took 6 of 21 outbound services (29%) in Period 2 2026-27 — the largest outbound destination from Grangemouth, arriving within 15 minutes on 100% of trips.

Source: Gauge Intelligence NROD-derived journey data, Period 2 2026-27. Total outbound services count every journey originating at any Grangemouth terminal TIPLOC, including services to destinations not yet named in the inland-terminal registry; rows are restricted to registered inland-terminal destinations, so the share column shows each terminal’s slice of total outbound traffic and the row counts will not sum to the total. Destinations with a published archive page link to that page; destinations named in the registry but not yet published render as plain text. The bracketed range on each within-15-minutes figure is the 90% confidence range given the sample size; terminals with fewer than 5 services in the period show a dash. Cancellations are excluded. Lens: supply-chain (port-origin destination-attributed) — see league-table methodology.

What the 15-minute threshold hides

Half of Period 2 2026-27 services arrived early — the median was 3 min ahead of timetable. The long tail the A2F binary misses: 5% of services ran +1 min or more late, and 1% arrived over +5 min late. The 15-minute A2F threshold sits at the 100th percentile — 0% of services exceeded it.

Median arrival delay is 4 minutes later than Period 1 2026-27 (median was -7 min then, -3 min now).

24 services with confirmed terminal arrival in Period 2 2026-27. A2F is binary at 15 minutes — this distribution surfaces what the headline figure does not show. National 99th percentile across all freight operators: 95 min.

Baseline (Period 1 2026-27): median -7 min, p99 +35 min. Period-on-period median shift +4 min.

Daily on-time arrivals across Period 2 2026-27

Daily on-time arrivals are up 10.4 percentage points on Period 1 2026-27 (90% then, 100% now).

Source: Gauge Intelligence NROD-derived journey data, Period 2 2026-27. A service is counted on time when terminal arrival falls within 15 minutes of schedule. Days with no scheduled services (typically Sundays) render as gaps — a missing bar means no measurement, not a value at zero. Red bars flag days that triggered a statistical signal — see anomaly-detection methodology.

Cancellation rate

In Period 2 2026-27, 7% of scheduled services were cancelled (2 of 27) — 3.4pp above the national mean of 4% across all freight operators; FOC traction, crew, and terminal decisions accounted for the largest share.

Cancellations are up 1.50 percentage points on Period 1 2026-27 (6% then, 7% now). The largest shifts in the responsible-party split are reported in the table below.

Attribution

Cancellation rate in Period 1 2026-27 was 6% across 51 scheduled paths. The current period is up 1.50 percentage points on Period 1 2026-27.

Source: NROD/TRUST activation feed and BPLAN scheduled paths, Period 2 2026-27. Cancellation rate = (post-activation + pre-activation cancellations) ÷ scheduled or activated paths. Pre-activation cancellations are TRUST CANCEL messages on schedules that never activated; post-activation cancellations have an activation and a CANCEL event. The bracketed range beside the headline rate is the 90% confidence range on the cancellation proportion given the sample size. Cause attribution uses the responsible-party mapping of the recorded cancellation reason code; see delay-attribution methodology.

Commercial licence

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.

• Schedule 8 net position
• Why late — delay attribution
• Schedule 4 possession exposure
