Port of Newport — Period 13 2025-26 (1–28 March) report
Port of Newport received 63 monitored inbound services in Period 13 2025-26 — a small monitored sample. 87% arrived within 15 minutes of schedule across 53 completed arrivals (90% Wilson interval 77–93%), against a national freight benchmark of 89% over 17,665 completed services. All 53 completed arrivals were handled by a single operator. Inaugural Port of Newport period report; no prior-period comparison is published.

- Cite the methodology in port operations and corridor reviews.
Who can use it
Port operations leaders · Terminal allocators · Rail journalists
Across Period 13 2025-26, roughly 0 inbound trains a day arrived at Port of Newport more than 15 minutes late — about 1 in 10 of 46 completed arrivals over the 28-day period, 5 late arrivals in total. This is a small monitored sample of 63 scheduled services across the five Newport Docks TIPLOCs; the 90% Wilson interval is correspondingly wide. All 46 completed arrivals were operated by DB Cargo UK, making this a single-operator steel flow inbound along the South West & Wales to Midlands corridor. Figures are drawn from Network Rail's NROD/TRUST feed. The Period 12 2025-26 trailing window is below the threshold for a stable comparator; subsequent periods will carry the comparison against the prior period. Cancellations are reported separately below.
Operators at Newport-inbound
DB Cargo UK ran the most newport-inbound services in Period 13 2025-26 (46 of 46 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 Port of Newport
Margam Steel Terminal took 37 of 42 outbound services (88%) in Period 13 2025-26 — the only registered inland destination with services in this period, arriving within 15 minutes on 89% of trips.
| Inland terminal | Outbound services | Share | Within 15 minutes |
|---|---|---|---|
| Margam Steel Terminal | 37 | 88% | 89% (78–95%) |
Source: Gauge Intelligence NROD-derived journey data, Period 13 2025-26. Total outbound services count every journey originating at any Port of Newport 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 13 2025-26 services arrived on time or better. The long tail the A2F binary misses: 5% of services ran +34 min or more late, and 1% arrived over +44 min late. The 15-minute A2F threshold sits at the 87th percentile — 13% of services exceeded it.
| Percentile | Arrival delay |
|---|---|
| 50th percentile (median) — A2F threshold sits at the 87th percentile | +0 min |
| 75th percentile — A2F threshold sits at the 87th percentile | +1 min |
| 85th percentile — A2F threshold sits at the 87th percentile | +4 min |
| 90th percentile | +28 min |
| 95th percentile | +34 min |
| 99th percentile | +44 min |
46 services with confirmed terminal arrival in Period 13 2025-26. A2F is binary at 15 minutes — this distribution surfaces what the headline figure does not show. National 99th percentile across all freight operators: 98 min.

Daily on-time arrivals across Period 13 2025-26
Range 50%–100% across 28 days. Weekend mean 100% vs weekday 89% (+11.2 percentage points). Mean 90%. (17 of 28 days had recorded services.)
Period 13 2025-26 daily A2F averaged 99% across 17 observations. One or more observations fell outside the expected range (12 day(s) beyond the expected range; 10 run(s) of two-of-three days off-mean; 11 run(s) of four-of-five days off-mean; 4 run(s) of eight consecutive days on one side of the mean), indicating an unusual event rather than ordinary noise.
Source: Gauge Intelligence NROD-derived journey data, Period 13 2025-26. 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 13 2025-26, 25% of scheduled services were cancelled (16 of 63) — 11.9pp above the national mean of 14% across all freight operators; FOC traction, crew, and terminal decisions accounted for the largest share.
| Scheduled or activated paths | 63 |
| Cancelled (post-activation + pre-activation) | 16 |
| Cancellation rate | 25% 18%–35% |
| National cancellation rate (all freight) | 14% |
Attribution
| Responsible party | Cancellations | Share of cancelled |
|---|---|---|
| Network Rail infrastructure and possessions | 2 | 13% |
| FOC traction, crew, and terminal decisions | 11 | 69% |
| Third party | 0 | 0% |
| Unattributed | 3 | 19% |
Source: NROD/TRUST activation feed and BPLAN scheduled paths, Period 13 2025-26. 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.
What this page does not measure
Pre-activation cancellations fall outside the dataset: TRUST requires an activation event before it records a journey, so services cancelled before activation produce no TRUST record. VSTPs are excluded from the path-utilisation denominator because no Working Timetable row exists against which to measure them. Journeys without a confirmed terminal arrival are excluded from the delay distribution. The 15-minute A2F threshold is a regulatory artefact, not a natural cut-off — the "What the 15-minute threshold hides" panel surfaces the distribution behind that line.

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
Revisions
No revisions to date.
A revision restates a published figure because the upstream data changed, typically a Network Rail delay-attribution refresh. The minor tier is corrected in the next release; cells affected carry an (r) flag. The intermediate tier triggers immediate amendment with an (r) flag. The wholesale tier is flagged at the top of the page and notified directly to operators and rail journalists subscribed to revision alerts.
Corrections
No corrections to date.
A correction fixes an error in the published output: an arithmetic slip, a typo, a mis-rendered chart. Revisions are different; they restate a figure because the upstream data changed. The distinction matters because corrections never silently rewrite a published number.
