I've made some modifications to some whistle signs (reached out to the originators, but never heard back). I combined the horn sequencer to the Whistle/Xing primary script so you don't need the sign PLUS the horn sequencer trigger. I also made some changes to the sequencer so the horn plays much smoother. Additionally, I added a speed check so if the train is moving at a slower speed, the time the sequencer starts will be adjusted. For example, just getting started or running under yellow or slowing down for the next speed limit. The recommended distance placements are in the descriptions. I did stop at 70 mph, so those of you running faster trains will need to adjust accordingly.
