Descriptiontext

Zonegreen Limited is a Sheffield-based, privately held engineering company founded in 1999 that specializes in rail depot personnel protection systems. Its core product, the SMART Depot Personnel Protection System (DPPS™), is positioned as a global market-leading solution for safeguarding rail staff in depot environments, complemented by the Points Converter (which enables automation and remote operation of manual hand points/switches), Advanced Interlocking Solutions (electronic and mechanical interlocking integrated with Overhead Line Equipment, third rail, and vehicle movements), and a Maintenance Packages service line that supports the full product lifecycle under a 'Safety by Design' philosophy.

The technology stack combines proprietary hardware, embedded software, and cloud computing to deliver connected rail safety solutions. Zonegreen sells primarily through direct enterprise field sales to railway operators, train operating companies, rail OEMs (Alstom, Siemens, Hitachi, CAF), engineering contractors, and facilities managers, with custom installation and integration at each depot. A recurring revenue component is generated through comprehensive maintenance packages covering the installed base, layered on top of one-off hardware and system sales.

The company serves a global customer base spanning the United Kingdom, continental Europe (France, Germany, Spain, Ireland), the Middle East (UAE, Qatar), and the Asia-Pacific region (Australia, New Zealand, Japan), with named customers including Network Rail, Eurostar, Dubai Metro, Doha Metro, Kiwi Rail, LNER, GWR, South Western Railway, Chiltern Railway, Northern Railway, Govia Thameslink, Irish Rail, and others. The business is operated as an independent private limited company with an employee base in the 11–50 range and no disclosed external investors, funding rounds, or parent company.
