so i plan on added a bluetooth based control system to all of my locomotive with an arduino based sound system which requires editing the sound files which i did in Audacity in much the same way that rik (the owner of the Peckforton Light Railway) did however the sounds i used were sourced from audio clips from a Canadian National Railways FP9a and an old tractor
you can use any files in that link that are numbered please only use the numbered files the other files are unedited
here is a link to the blog post for how to use these sound files
