@Adriatic posted:What triggers brake/flange squeal on my TMCC E-33 or railsounds Berk Jr tender?
The R2LC serial data comes over and the RS board decodes if you're braking based in the serial data stream.

Could it? Maybe. However, that filter would likely change for each type of horn and/or whistle. Also, I have serious reservations about how reliable that triggering would be.
