Birch Coppice (BIFT) — Period 1 2026-27 (29 March – 25 April) report
Birch Coppice received 73 monitored inbound services in Period 1 2026-27 — 86% arrived within 15 minutes of schedule across 69 completed arrivals, against a national freight benchmark of 89%. The -2 percentage-point move on Period 13 2025-26 sits within plausible sampling variation; the ranges around each reading overlap.

Context
ORR publishes aggregates only; this page publishes destination-attributed terminal-level data. Material to yard planning, terminal allocation, and inland-terminal performance reviews.
What you can do with it
- Track arrivals reliability at an inland terminal, attributed by destination TIPLOC.
- Compare operator-by-operator reliability on services inbound to a single terminal.
- Cite the methodology in terminal operations and corridor reviews.

Inland terminal operators · Yard planners · Rail journalists
Across Period 1 2026-27, roughly 0 inbound trains a day arrived at Birch Coppice more than 15 minutes late, about 1 in 6 of 68 completed arrivals over the 28-day period, 12 late arrivals in total. Figures aggregate every monitored journey arriving at the five Birch Coppice TIPLOCs on the Kingsbury branch (KNGSBCE, KNGSBCG, KNGSBOS, KNGSBYG, KNGSBEM) inbound along the West Coast Main Line, drawn from Network Rail's NROD/TRUST feed. Birch Coppice is Maritime Transport's Birmingham Intermodal Freight Terminal (BIFT) — Maritime operates the terminal; the inbound services are run by the freight operators. Cancellations are reported separately below.
Operators at Birch-Coppice-inbound
GB Railfreight ran the most birch-coppice-inbound services in Period 1 2026-27 (44 of 68 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.

What the 15-minute threshold hides
Half of Period 1 2026-27 services arrived within +5 min of timetable. The long tail the A2F binary misses: 5% of services ran +41 min or more late, and 1% arrived over +95 min late. The 15-minute A2F threshold sits at the 85th percentile — 15% of services exceeded it.
Median arrival delay is essentially unchanged on Period 13 2025-26 (5 min then, 5 min now).
| Percentile | Arrival delay |
|---|---|
| 50th percentile (median) — A2F threshold sits at the 85th percentile | +5 min |
| 75th percentile — A2F threshold sits at the 85th percentile | +9 min |
| 85th percentile — A2F threshold sits at the 85th percentile | +14 min |
| 90th percentile | +26 min |
| 95th percentile | +41 min |
| 99th percentile | +95 min |
68 services with confirmed terminal arrival in Period 1 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: 100 min.
Baseline (Period 13 2025-26): median +5 min, p99 +107 min. Period-on-period median shift +0 min.

Cancellation rate
In Period 1 2026-27, 7% of scheduled services were cancelled (5 of 73) — within the national mean of 7%; Network Rail infrastructure and possessions accounted for the largest share.
Cancellations are down 3.90 percentage points on Period 13 2025-26 (11% then, 7% now). The largest shifts in the responsible-party split are reported in the table below.
| Scheduled or activated paths | 73 |
| Cancelled (post-activation + pre-activation) | 5 |
| Cancellation rate | 7% 3%–13% |
| National cancellation rate (all freight) | 7% |
Attribution
| Responsible party | Cancellations | Share of cancelled |
|---|---|---|
| Network Rail infrastructure and possessions | 2 | 40% |
| FOC traction, crew, and terminal decisions | 1 | 20% |
| Third party | 0 | 0% |
| Unattributed | 2 | 40% |
Cancellation rate in Period 13 2025-26 was 11% across 122 scheduled paths. The current period is down 3.90 percentage points on Period 13 2025-26.
Source: NROD/TRUST activation feed and BPLAN scheduled paths, Period 1 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 this report doesn't yet carry
Three blocks routinely carried on more mature period reports remain absent, and the gap is disclosed rather than papered over:
- SPC process-behaviour chart. The terminal has four weekly A2F points in Period 1 2026-27; the signal rules require eight before a stability or anomaly claim can be made. The block is suppressed.
- Median-polish operator-by-week matrix. Two operators clear the minimum-journeys threshold across the period (GB Railfreight 45, DB Cargo UK 24) but the per-week cell depth is too thin for a defensible row-by-column decomposition, so no matrix is published.
- Compositional delay-reason breakdown. Network Rail's Historic Delay Attribution feed for Period 1 2026-27 has not been imported at the as-of date of this report. Raw percentage-share comparison is misleading when shares are constrained to sum to 100% — an increase in any one cause forces a decrease in another — so the block is suppressed rather than substituted with a naked share. See the delay-attribution methodology.
Each of these unlocks as baseline depth grows. The weekly SPC threshold and the operator-by-week matrix become candidates for inclusion as the trailing window deepens through 2026-27.
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
Three further reads sit behind the commercial licence: a Schedule 8 net-position figure netting the FOC-to-Network-Rail differential against payments the other way; a full DAPR breakdown attributing each cause-code's contribution by sample weight; and a Schedule 4 possession-exposure read tracing how planned blockades intersect terminal-bound path allocation. None is yet substantively informative at Birch Coppice's current baseline depth — the period count that suppresses the SPC chart above leaves each licensed read with too few points to anchor. The licensed access page sets out the methodology behind each.
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.
