Baldwin and Francis can supply robust, high-quality Distribution Interface Transformer Assembly’s (DITA). Tailored to the customer’s specific requirements & with innovative Distribution Feeder Soft-Start (DFSS) technology also available, it has been designed and developed in compliance with current Network Rail specifications.
DITA applications
- Interfacing and segregation between Class I and Class II installations
- Division of a signalling power supply into smaller sections (reduced touch potentials and ‘first fault’ current, better insulation monitoring)
- Voltage boost for long signal feeders
- Minimisation of stray traction current when diverse traction earthing arrangements are employed

Completed Projects
Core Valley Lines Transformation Project
The Core Valley Lines (CVL) programme of works forms a significant part of the South Wales Metro project with a budget to both improve and renew existing assets. As part of these improvements, B&F were contacted to supply various signalling power control equipment and supporting services to ensure continuity across the project; initially starting with the supply of GRP ASP units at Aberdare and Merthyr Tyfdil.
East Coast Main Line DNOs
The East Coast Main Line improvement project is a 5+ year long project to enable faster, quieter and more environmentally friendly trains to run between Edinburgh and London. As part of these improvements, B&F were contacted to supply various DNO Cubicles across the route.
Kings Cross Remodelling Project
A major part of the East Coast Upgrade by Network Rail was a multi-million-pound investment in renewing track, signalling and overhead line equipment at King’s Cross.
B&F Expand Rail Capabilities to Subways
The subway, which carries millions of passengers each year, is one of the oldest subway systems in the world. This brownfield project would see a complete transformation including the provision of a brand-new Integrated System with new Rolling Stock, Depot Equipment, Construction Works and Fixed Equipment.
The Trans Pennine Route Upgrade (TRU)
As part of TRU project, a multi-billion-pound long-term railway infrastructure project that will improve connectivity in the North of the UK, various improvements and renewals are being completed across the North.
Northumberland Park DNO Cubicle
As part of the WAML upgrade project, B&F supplied GRP DNO to the client who required a 2 week turn around due to unforeseen complications.
Wessex Route Project
The Wessex rail upgrade project is a longstanding project with an investment of £2bn to improve the railway infrastructure from across the South West and into London.
