I have been working on an activity for the San Diego & Arizona Railway 2.1.
I made invisocars to match the horn & whistle sounds for some of the engines that I have selected for the activity.

The switch engines and GP's for SDA use the default diesel invisocar because the default sound is a GP38.

The rest of the engines should be part of the wagon name.
