Mechanics

During the design phase of railway infrastructures, equipment and rolling stock, or during the qualification process, tests and measurements are essential to evaluate mechanical characteristics of the products and equipment.

DESCRIPTION

From the measurements performed and depending on the client’s requirements, Eurailtest will, if requested:
– Perform assessments
– Suggest optimisations
– Carry out expert analyses
on the mechanical behaviour of a vehicle or a sub-system.
