Horn Track for Advanced Trains

This mod adds a track for Advanced Trains that automatically activates the horn or whistle of any train that passes over it.

Features:

• Horn tracks can be customised to play different patterns.
• Horn tracks are available for standard tracks and tieless tracks.
• Trains can be filtered with ARS rules (requires Advanced Trains Interlocking).

Patterns

A pattern consists of a sequence of space-separated notes in the form [INTENSITY*]DURATION, where INTENSITY indicates the horn volume on a scale from 0.0 to 1.0, and DURATION indicates the length in seconds.

You can insert a delay with 0*DURATION.

Two adjacent words of the same intensity will automatically insert a delay. You can prevent this by adding a zero-length delay with 0*0.
