Colas Rail — Period 1 2026-27 (29 March – 25 April) report

Daily on-time arrivals across Period 1 2026-27

Daily on-time arrivals are up 0.8 percentage points on Period 13 2025-26 (92% then, 93% now).

Source: Gauge Intelligence NROD-derived journey data, Period 1 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 1 2026-27, 3% of scheduled services were cancelled (75 of 2558) — within the national mean of 7%; FOC traction, crew, and terminal decisions accounted for the largest share.

Cancellations are down 2.10 percentage points on Period 13 2025-26 (5% then, 3% now). The largest shifts in the responsible-party split are reported in the table below.

Attribution

Cancellation rate in Period 13 2025-26 was 5% across 2,540 scheduled paths. The current period is down 2.10 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.

Colas and peer operators, by shared corridor

The per-corridor league table for Colas is deferred while the v1.0 industry review edition corrections inbox remains open. Comparative ranking against peer freight operators on each shared corridor returns at v2.0 general availability, after the launch-cohort corrections cycle closes and the dataset has been reviewed by industry readers. The league-table methodology sets out the partial-pool estimator and the Wilson interval framework the panel will use; the release cadence page sets out the four exit criteria for v2.0 and the schedule against which they are measured.

Source: Gauge Intelligence NROD-derived journey data, Period 1 2026-27. Single-operator Wilson intervals on shared corridors continue to appear in the per-corridor breakdowns above; the per-corridor ranking against peers is the panel deferred here.

What the 15-minute threshold hides

Half of Period 1 2026-27 services arrived early — the median was 5 min ahead of timetable. The long tail the A2F binary misses: 5% of services ran +21 min or more late, and 1% arrived over +87 min late. The 15-minute A2F threshold sits at the 93th percentile — 7% of services exceeded it.

Median arrival delay is essentially unchanged on Period 13 2025-26 (-5 min then, -5 min now).

1,652 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 +72 min. Period-on-period median shift +0 min.

Intraday pattern

Fri (95%) is 3.2 percentage points above Mon (92%), the weakest day in Period 1 2026-27.

The 08-12 departure window records 90% A2F — 6.6 percentage points below the 12-16 peak (96%) in Period 1 2026-27.

The day-of-week spread is narrower by 2.1 percentage points on Period 13 2025-26 — punctuality varies less across the working week than the prior period.

By day of week

By departure hour

Baseline (Period 13 2025-26) day-of-week spread delta: -2.1 percentage points.

Source: NROD-derived journey data, Period 1 2026-27. Day-of-week is ISO (Mon=1..Sun=7). Hour windows are 4-hour buckets keyed off TRUST origin_dep_timestamp. A2F threshold is 15 minutes on terminal arrival. 90% Wilson interval on each cell's proportion.

Path utilisation

Activated 1,303 of 2,558 scheduled paths (51%, 90% range 49%–53%) in Period 1 2026-27 — +18.9 percentage points above the national freight-operator mean of 32%. 1,255 ghost paths (scheduled, not activated).

In plain terms: a scheduled path is a freight slot reserved in Network Rail's Working Timetable. An activated path is one where TRUST recorded the train starting its run. A ghost path is a scheduled slot that produced no activation — 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 for how scheduled, activated, and ghost paths are derived.

Free-tier: operator-total activation rate and ghost count for Period 1 2026-27. Per-corridor path utilisation, per-path scheduling-pattern analysis, and spot-contract renewal guidance are released to commercial-licence subscribers. The activation rate measures Working-Timetable path-days that materialised as activations — not operator delivery performance against intent. Capacity-reservation paths and contingency optionality in the WTT mean a sub-100% rate is a transparency datum, not a delivery indictment.

STP precedence (C > O > N > P) is applied per (train_uid, date) pair via Schedule.effective_for; STP-cancelled path-days are excluded from the denominator. VSTP activations (no Schedule row) are excluded from both numerator and denominator. 90% Wilson interval on the proportion. National FOC mean computed across the known FOC universe in the same window — see path-utilisation methodology.

Schedule 8 net position

Bilateral Schedule 8 settlement runs at two rates under CP7: operators pay Network Rail £51.98 per minute of operator-attributed delay; Network Rail pays operators £25.81 per minute of NR-attributed delay. The asymmetry produces a net position on every period for every operator; its sign and size depend on the period's bilateral delay-minute mix at rates that do not move within a control period.

The bilateral net position for Period 1 2026-27 on services operated by Colas Rail, together with the per-corridor decomposition, the rate-gap counterfactual against an equal-rate benchmark, and the period-on-period swing, is released to commercial-licence subscribers.

Per-corridor and per-day Schedule 8 net-position figures, and the full responsibility-party breakdown, are released to commercial-licence subscribers.

Delay attribution party split

Across 107 attribution rows totalling 251 delay minutes in Period 1 2026-27 for services operated by Colas Rail, Network Rail carries 100%, operators carry 0%, and third parties carry 0% of the attributed delay minutes.

Network Rail's share of attributed minutes is up 49.2 percentage points on Period 13 2025-26 (51% then, 100% now). Operator share moved down 22.7 percentage points alongside — the bilateral mix of attributed minutes shifted, not the total volume of delay.

Baseline (Period 13 2025-26): NR 51%, operator 23%, third party 27%. Period-on-period NR share shift +49.2 percentage points.
