Citation guide

Gauge Intelligence publications are issued as dated reports under a public archive licence. Each report covers a defined time window, uses a fixed methodology version, and is identified by its URL path. When figures change after publication (due to source data revision, calculation correction, or methodology update), a correction notice is appended to the original report and logged in the correction register.

How the citation appears on report pages

Each period-report page renders the same metadata as a definition-list grid in the “Publication record” block at the foot of the article — publisher, published, data as of, URL, licence, plus editor and contact. The values are equivalent to the sentence form above; copy whichever suits the publication style of your reuse.

Citing a specific figure

When citing a specific figure from a report, include the report section and the period covered.

Gauge Intelligence found that the GEML corridor recorded 81% A2F punctuality across 2591 freight services in Period 13 2025-26 (1–28 Mar 2026), against a >90% national FCaL benchmark (GEML Corridor Period 13 2025-26 Period Report, Gauge Intelligence, 30 April 2026, §Punctuality).

For Schedule 8 exposure figures, note the rate basis:

Network Rail’s Schedule 8 counterfactual exposure to GEML freight operators — the delta from a zero-NR-delay benchmark — is computed at the CP7 NR-to-FOC rate of £28.42/min (2025-26 CPI-indexed from £25.81 base — see CPI indexation methodology), covering Period 13 2025-26 (1–28 Mar 2026) (GEML Corridor Period 13 2025-26 Period Report, Gauge Intelligence, 30 April 2026, §Schedule 8).

Citing corrected figures

If a report has been corrected after publication, cite the correction:

Gauge Intelligence. [Report title]. [URL]. Original publication: [date]. Correction issued: [date]. Retrieved [access date]. Licence: CC BY-NC 4.0.

The original figure and the corrected figure are both preserved in the correction notice.
