Train bells occasionally not stopping

[Scary-Jello]

I've been working on a map that features a train near point A, i've followed this tutorial on how to make train and it works fine. However, very occasionally, the 2 ambient generic entities that play the bell sounds just, never stop, seemingly at random. Sometimes the sound loops on both entities, sometimes just one of them, sometimes it runs smoothly no matter what.

My current setup is attached:

The bells are set to a volume of 0 by default, and turned to 10 when a timer goes off, once the train passes a path_track, the bells are set to 0 again.

Any help on how to fix this or even why it happens would be much appreciated!

Instead of using Volume inputs, try using PlaySound (Plays a sound, and if it has looping in the Flags tab checked, it repeats basically forever until it is stopped by an input) and StopSound (Stops any looping sounds) inputs for the ambient_generic entities.

Thank you, I saw a thread a while ago saying to use volume inputs because using PlaySound and StopSound only works for looping sounds, but I, for some reason, never thought to flag them as looping.
