Suite d’outils de visualisation de voie en 3D

3D Tools Suite

Connection to a 3D track visualisation application as an extension of the Operational Simulator.


Our products cover a large panel of tools dedicated to testing, training, research and demonstration. These products are the result of 20 years of expertise in the field of ERTMS/ETCS. These products are available off-the-shelf but can easily be customised to specific needs, especially interfaces with other test or simulation systems.

Developed tools

Several tools developed by ERSA in the frame of European projects are widely used by the sector, such as the Test Sequence Wizard (TSW) and the Test Sequence Debugger (TSD).

The ERSA Performance

The TSW is used to create the Test Sequences which will serve as basis for tests of the on-board products delivered by Railway Industries. The TSD is a functional simulator of all the on-board functions of ETCS. It is widely used to calibrate, tune and verify the Test Sequences.
