Vehicle modelling

Vehicle modelling

The first step in getting your vehicle approved.

Vehicle models are required for a gauging assessment, which in turn is required for permission to operate. Accurate vehicle models reduce the issues arising from a gauging assessment.

We have vast experience in vehicle modelling and are experts in the Rail Industry Standard RIS-2773-RST modelling format. We use VAMPIRE® modelling and simulation to reduce uncertainty and risk.

How it works


Vehicle models are created using dimensions taken from a design drawing. If insufficient information is available then we use our laser scanner to measure the vehicle.

Vehicle models use suspension movements which are calculated using a software package such as VAMPIRE®.  We are expert VAMPIRE® users and generate suspension movements as necessary.

Our VAMPIRE modelling is a value driven process. By using VAMPIRE we reduce the risks of additional costs caused by the use of estimated movement data.  Bespoke movement data ensures that accurate clearances are calculated.
