Trains consist of vehicles connected using coupling systems, draw gears, chains, or solid bars. Rail vehicles, or rolling stock, can be custom-defined with specific dimensions and characteristics, such as mass, strength, geometry, braking and driving force capabilities, and bogie configurations. DigitalTrains™ also offers a library of vehicle templates to get started with your train assembly.
Key Vehicle Properties
Vehicles have unique geometrical properties and mass.
