Welcome to Class37.co.uk

Class37.co.uk is a working archive dedicated to preserving the operational record of the English Electric Type 3 (Class 37) across the UK rail network. Whether you are a researcher, archivist, or enthusiast drawn to the roar of EE Type 3s, this site offers a structured record of the movements, diagrams, headcodes, and allocations that defined an era.

Here you will find:

• Current Operations — a daily record of Class 37 workings, providing continuity between present‑day activity and historical context.
• Historical Movement Logs — cleaned, de‑duplicated, and formatted for long‑term preservation, with padding and transcription errors removed.
• Operational Diagrams — reconstructed from primary sources, cross‑checked against headcodes, allocations, and regional overlays.
• Contextual Notes — annotations highlighting discrepancies, corrections, and the reasoning behind data reconciliation.

Every entry is treated as a historical record, with emphasis on provenance and repeatable methodology. The aim is not only to preserve the operational story of the Class 37, but to provide a framework that other archivists can interrogate, reuse, and build upon.

This is a living archive: continually refined, corrected, and expanded. It is built for those who value the mechanics of preservation as much as the locomotives themselves.
