System engineering

From system and implementation concepts, technical project management and development of tender specifications to commissioning and system integration.

NEXTRAIL defines successful teamwork in a project as processes that seamlessly intertwine. For all technical, functional and operational aspects. With the highest level of professional expertise in all disciplines.

Wherever the future of rail is written. NEXTRAIL supports railway operators and manufacturers in the transition to the modernisation and digitisation of railways. Complex processes in which reliable and lasting effective results are achieved within tight time frames.

The systems engineering expert teams at NEXTRAIL focus on constructive and cooperative collaboration as well as the perfect interdisciplinary interaction of our technology and departmental experts. This is how we provide reliable support from system design and gathering requirements, the creation of guidelines, support for tendering processes, and taking charge of technical project management and approval processes through to roll-out with commissioning and system integration.

To this end, we draw up service descriptions, implementation concepts, LCC evaluations and develop tendering criteria, requirement specifications and interface descriptions. All this from a single source – so that a holistic view of technical, functional and operational aspects is always maintained and that losses due to communication are a thing of the past.
