• Assessments, safety cases and approvals
  

Modern rolling stock can feature complex, smart technologies and are typically designed for a long lifespan under extreme conditions, normally 30 years. They represent significant capital expenditure for train operating companies and leasing companies. The procurement of new rolling stock, therefore, must be carefully managed and assessed. ENOTRAC offers railway operators comprehensive support at all stages of the procurement process, from the writing of calls for tender documentation (as per World Trade Organisation guidelines), and the objective evaluation of bids, to the approval of design documentation through to the management of the vehicle acceptance process.

Through our engineering expertise, we provide concrete technical solutions for rolling stock manufacturers in the protection of high-voltage circuits, interference current monitoring, filter design, or the optimisation of regenerative brake characteristics, for example. ENOTRAC customers also benefit from our experience and software tools in other specialist areas, including traction power supply, energy consumption calculations, and compatibility with signalling systems.

The economic, technical and operative lifespan of existing rolling stock can be significantly prolonged through the replacement of obsolete systems by more powerful or cost-effective solutions and through the use of the most advanced technologies available. Such an approach favours best-value-for-money and promotes a responsible and sustainable allocation of resources. ENOTRAC engineers are delighted to meet the challenge of modernising existing rolling stock.
