Your Partner for Rail Engineering

Rail

Inter-Informatics offers turn-key services covering feasibility studies, concept, development, 3D design, 2D documentation, FEM analysis, SW support, jig/ tool design and manufacturing; and vehicle manufacturing support.

Our highly qualified design team routinely deals with the standards and processes of the rail industry. We are certified according to the ISO9001 (quality system); EN15085-2, certification level CL4 (standards for the design of welded constructions).

The focus is on the design of trams, locomotives, diesel and electrical multiple units and coaches.

Rail vehicle expertise:

Development of the interior for the electrical multiple unit rail vehicle.

We undertake new design and modification of vehicle interiors; including passenger compartments and driver cabins. We deliver the design of installation of interior components and equipment, and offer tender documentation, as well as technical evaluation of bids from individual component suppliers. Inter-Informatics covers the whole development process. From concept via 3D and 2D documentation to vehicle manufacturing support.
