Purpose

Network Rail’s role is to deliver a safe and reliable railway infrastructure. The company carefully manages and delivers thousands of projects every year.

MDU stands for Maintenance Delivery Unit. The purpose of an MDU is to provide a physical base for maintaining the railways. MDUs come in many forms and are design specific in nearly all situations. There are a great deal of similarities and good practice that should be shared between them that this guidance manual focusses on. This document should assist the project teams designing and delivering new MDUs, to achieve a high standard and to maintain consistent quality across the routes.

This guidance should be used to support new and existing MDU design across the Network Rail estate.
