Description of Project
Laira TMD is a railway Traction Maintenance Depot situated in Plymouth, Devon, England.
The depot is operated by Great Western Railway (GWR) and is mainly concerned with the overhaul and daily servicing of their fleet of high-speed trains and diesel multiple units (DMU) used on local services.
Our design encompassed the amendments required at the depot to facilitate maintenance activities in support of the introduction of new Hitachi Rail AT300 rolling stock.
Depot Design Services
It is not unusual for the client’s mandate and scope documents to be rather brief, however, with guidance from the Form 001/002: Approval in Principle, Statement of Design Intent submission and using our extensive experience, Emeg was able to guide the client through the principles of train servicing design within depots, using apron mounted service points for such items as:
- e-vac™ Controlled Emission Toilets (CET)
- Apron hot & cold water points
- Plantroom domestics
- Fuel, engine oil, hydraulic oil, coolant & e-mix™ AdBlue fuel additive
Further to site surveys, data logging of existing services, load studies and coordination with end users, we used our experience along with ‘lessons learned’ processes that we extract from each project to deliver a fully coherent and site-specific design.
All elements of depot services design were completed under the scope of the project data management plan to a Level 2 BIM strategy. As part of the ‘Infrastructure Projects’ process plan, our design team delivered fully coordinated 3D models using Bentley Microstation with project data management on the preferred NWR ProjectWise platform.
Fully Coordinated & Integrated Depot Design Services
It is common in today’s construction environment to ensure that all disciplines are required to coordinate and build their designs in real-time 3D models to be shared for review and discussion as prescribed in the NWR Engineering Management Plan.
The use of such software and review processes enable the design team of all disciplines to come together to seek to prevent problems before they arise and thus develop a coherent coordinated design.
Through the process of interdisciplinary design meetings and reviews, the fully developed design for all elements from all disciplines can achieve sign-off and approval by the client prior to build. This ensures less abortive works for both design and construction and leads to the client being fully aware of what is being provided to match their specifications and expectations.
Trackside equipment is required to be gauge-clear of any rolling stock envelope and modelling allows us to ensure equipment and services not only match with civils designs but allow for moving vehicles – all prior to construction.
By using forward-thinking designs, we were able to achieve the client’s required output without the need for greater civils structures to accommodate equipment. Design and 3D construction techniques allow us to alter what used to be “standard” assemblies and make them bespoke. Our expert rail teams are constantly seeking to provide innovations and enhancements for all depot systems, creating solutions tailored to the specific requirements of each individual site.

Howdon Satellite Depot
With the existing Nexus Metro depot at Gosforth, North Tyneside undergoing redevelopment works, Howdon needed to be brought online as an additional depot facility quickly and safely.
Blackpool Depot
This project involved the replacement of existing depot services including sanding, CET, Carriage Wash Machine & tanking water to the new servicing aprons.
Blackburn Depot
The Northern Hub programme was developed to increase capacity, line speed & connectivity throughout the North West. Blackburn is a new depot introduced to accommodate the additional rolling stock.

A new 10,000m² facility for Bombardier Transportation in Derby to enable the final test and sale of trains for the Crossrail project.
Euston Station Remodel
The project consisted of the provision of new – and the refurbishment of existing – retail spaces at Euston Station.
Northampton Castle Station Redevelopment
A new ‘gateway’ station building and footbridge has been constructed to replace the existing station along with associated works including the demolition of the existing station.
