Maximum vehicle volume in WagonFit computes the largest geometry a vehicle can occupy along a given route, applying the real infrastructure constraints directly to the carbody geometry. Tunnel walls, platform edges, or any other element in the model all contribute to shaping the design envelope.

The result is available from the earliest stages of the project, giving the design team a calculated boundary to work within from the first sketch.
