4K RailRoad crossing test sounds and lights

I just made electronics for automatic sound and lighting effect on railroad crossings. This is the final test. I think it's cool 😁, just need to tweek the sounds better and I can made final pcb and solder it all together.
Electronics is made with arduinos, small MP3player, speaker, SD card wirth sounds and sensor that detect power consumption on a portion of track as a trigger.
It works perfectly wig no flaws.
