Anglo-Scottish — Period 2 2026-27 (26 April – 23 May) report
Anglo-Scottish recorded 71% A2F punctuality in Period 2 2026-27 (26 April – 23 May 2026) on 420 freight services, up 4 percentage points from 67% in Period 1 2026-27 on a smaller denominator. The intervals overlap with the prior period. PRELIMINARY at T+2; FINAL re-publication at T+35 after Network Rail's batch correction.

Context
ORR publishes no corridor-level freight performance; this page publishes operator-by-operator standings on the Anglo-Scottish corridor. Material to FOCs running Scottish intermodal and bulk services and to Network Rail's Scotland route performance team.
What you can do with it
- See every operator's Anglo-Scottish rank for the period, with partial-pool stabilisation for small samples.
- Quantify the corridor's CP7 exposure window.
- Cite the methodology, not a vendor's number, in negotiations.

What this page measures
The page makes three things possible. Every shared corridor is ranked: an operator's A2F sits next to active peer freight operators on that corridor, with a 90% interval around each figure. A period's CP7 exposure is computed from the operator's own services rather than national aggregates. The methodology behind each figure is named, dated, and reproducible, so track-access negotiations and academic citations can reference the published method rather than a vendor's number.
The Anglo-Scottish corridor carried 420 freight services between 26 April and 23 May 2026 (Period 2 of the 2026-27 rail year). Figures aggregate every monitored journey that traversed at least one of the corridor's 8 monitoring points, drawn from Network Rail's NROD/TRUST feed. This is the third published period for the Anglo-Scottish corridor; the prior period (Period 1 2026-27) carried 530 services at 67% A2F. The corridor connects Mossend and Coatbridge in the Scottish Central Belt to Carlisle and the WCML via Motherwell and Carstairs, with Grangemouth served via Falkirk Grahamston.
What changed since Period 1 2026-27
Corridor A2F punctuality stood at 71% over 420 services, with a 90% Wilson interval of 68%–75%. The headline share is 4 percentage points above the 67% recorded in Period 1 2026-27, and the intervals overlap with the prior period — the change sits within plausible sampling variation on the smaller Period 2 denominator. Services monitored fell by 110 on the prior period; the corridor-attributed figure does not separate timetable change, traffic mix, or absent operators from underlying corridor performance, and this report does not attribute the volume movement to a specific cause.
Daily on-time arrivals across Period 2 2026-27
Daily on-time arrivals are up 2.8 percentage points on Period 1 2026-27 (70% then, 73% now).
Range 44%–100% across 28 days. Weekend mean 77% vs weekday 71% (+5.4 percentage points). Mean 73%.
Period 2 2026-27 daily A2F averaged 80% across 28 observations. One or more observations fell outside the expected range (2 day(s) beyond the expected range), indicating an unusual event rather than ordinary noise.
Mean punctuality in Period 1 2026-27 was 70%. The current period is up 2.8 percentage points on Period 1 2026-27.
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, 5% of scheduled services were cancelled (22 of 431) — 1.1pp above the national mean of 4% across all freight operators; FOC traction, crew, and terminal decisions accounted for the largest share.
Cancellations are down 2.00 percentage points on Period 1 2026-27 (7% then, 5% now). The largest shifts in the responsible-party split are reported in the table below.
| Scheduled or activated paths | 431 |
| Cancelled (post-activation + pre-activation) | 22 |
| Cancellation rate | 5% 4%–7% |
| National cancellation rate (all freight) | 4% |
Attribution
| Responsible party | Cancellations | Share of cancelled |
|---|---|---|
| Network Rail infrastructure and possessions | 6 | 27% |
| FOC traction, crew, and terminal decisions | 14 | 64% |
| Third party | 0 | 0% |
| Unattributed | 2 | 9% |
Cancellation rate in Period 1 2026-27 was 7% across 563 scheduled paths. The current period is down 2.00 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.
What the 15-minute threshold hides
Half of Period 2 2026-27 services arrived within +8 min of timetable. The long tail the A2F binary misses: 5% of services ran +83 min or more late, and 1% arrived over +142 min late. The 15-minute A2F threshold sits at the 71th percentile — 29% of services exceeded it.
Median arrival delay is essentially unchanged on Period 1 2026-27 (8 min then, 8 min now).
| Percentile | Arrival delay |
|---|---|
| 50th percentile (median) — A2F threshold sits at the 71th percentile | +8 min |
| 75th percentile | +18 min |
| 85th percentile | +31 min |
| 90th percentile | +45 min |
| 95th percentile | +83 min |
| 99th percentile | +142 min |
409 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 +8 min, p99 +120 min. Period-on-period median shift +0 min.

Operator activity on Anglo-Scottish
Operator ranking on Anglo-Scottish for Period 2 2026-27 is deferred while the v1.0 industry review edition corrections inbox remains open. Publishing a corridor-level ranking against named operators before the launch-cohort corrections cycle closes would treat provisional figures as settled. The ranking returns at v2.0 general availability.
The framework the panel uses — partial-pool shrinkage toward the corridor mean, with rank order taken from the pooled estimate rather than the raw observed rate — is documented at league-table methodology. The schedule for v2.0 general availability is at release cadence.

Path utilisation
Ran 267 of 1,086 booked paths (25%, 90% Wilson 23%–27%) on Anglo-Scottish in Period 2 2026-27. 819 ghost paths (booked, not run).
In plain terms: a booked path is a freight slot reserved in Network Rail's Working Timetable that traverses this corridor's monitoring chain. A run path is a booked path that activated and produced a journey segment on the corridor. A ghost path is a booked slot that produced no corridor traversal — capacity held in the timetable that the operator did not use, typically because the underlying contract did not call the path or the service was withdrawn before the day. A sub-100% rate is normal: the Working Timetable carries contingency and capacity-reservation paths by design. See the path-utilisation methodology.
| Booked paths (non-STP-cancelled) | 1,086 |
| Run | 267 |
| Ghost paths | 819 |
| Activation rate | 25% 23%–27% |
Baseline (baseline) activation rate 28% across 1,271 booked paths; period-on-period delta -2.9pp.

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.
Commercial licence

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
Methodology
Corridor-level A2F punctuality is measured at the Anglo-Scottish corridor's 8 monitoring points spanning the route from Grangemouth and the Coatbridge / Mossend Central Belt cluster through Motherwell, Carstairs, and Lockerbie to Carlisle. A service is counted on time if it arrives at the terminal within fifteen minutes of schedule. The 90% confidence interval on each share uses the Wilson score method on the observed denominator. Severity bands across panels apply consistent thresholds: an SPC run-rule trigger on the daily series flags a day as anomalous, and gaps between operator rankings of more than 10 percentage points raise the peer panel into the alert band. See the anomaly-detection methodology for the SPC rules.
Operator rankings on the Anglo-Scottish corridor aggregate per operator via TRUST toc_id across every corridor segment traversal in the window, then apply partial-pool shrinkage so small-sample operators stabilise toward the corridor mean. Cross-view reconciliation across the four views (by operator, by destination, by flow, by corridor) is documented in the league-table methodology. Period boundaries and the data-as-of cutoff are documented in the data-window methodology. Data derives from Network Rail's NROD TRUST feed, processed via the Gauge Intelligence NROD pipeline.
The corridor's Schedule 8 net position, the Network Rail / freight-operator delay-attribution breakdown, the per-operator and per-path-quality ghost-path decomposition, the per-operator path-utilisation detail, and Schedule 4 possession exposure for the Anglo-Scottish corridor are released to commercial-licence subscribers. The intraday A2F pattern panel is deferred for corridor pages pending the segment-attributed intraday model; this exclusion is disclosed here per the analytical-rigour discipline applied across published pages.
Regulatory context
Network Rail's Control Period 7 obligation, fixed in ORR's PR23 conclusions, imposes a 1.3% target on the Freight Cancellations and Lateness (FCaL) metric by March 2029. A2F is the operator-perspective version of the same threshold: the cancellation-plus-lateness measure that drives the obligation. ORR's Freight rail usage and performance release records that its statistical publications do not compare results against targets. This page does, against the CP7 target and over time.
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.
