Volume and pitch of various train sounds can be controlled with a C# expression. Below is a list of variables that can be accessed during the simulation. The documentation is still incomplete and work-in-progress.

Most variables work only when tied to a certain physics component. Variables that are not applicable for specific use always return zero.

To access a variable in a C# expression, type get.[VariableName], for example get.Volume. The first word in the list below is the type of the value returned. Decimal means either float or double.

decimal get.Volume (returns the previous volume)
decimal get.Pitch (returns the previous pitch)
decimal get.VehicleRnd (returns a constant vehicle-specific random number between 0 and 1)
decimal get.SoundRnd (returns a constant sound/component-specific random number between 0 and 1)
decimal get.Rnd (returns a random number between 0 and 1)
integer get.RndInt (returns a random number between int.MinValue and int.MaxValue)
