Health and Safety Standard ISO 45001:2018


The manual helps provide direction and guidance on how as a company, we meet the requirements of all 3 standards. We continuously strive to improve our operations and processes. By engaging our entire team we gain an understanding of each activity, which enables TDI to control its Occupational Health & Safety risks and improve our company performance. The environmental aspect has also brought out the best in our people to minimise the impact on the environment. It is such a great achievement to receive certification by such a reputable brand as BSI.

TDI have successfully built and commissioned two of the world’s first Very light Rail vehicles. Our processes and ways of working have now been verified to reach the BSI standards for adherence to quality, environment and H&S performance. We are immensely proud of this achievement. It sets us up for continued success through our next wave of production vehicles. We look forward to delivering this continued support to our customers.
