honestly you have to find the best sound sample you can, hardly any amount of cleanup will make the sound better, it is very hard to remove any amount of Chuffing, grade crossing or locomotive bell ringing. easiest bet, but not always the most realistic sounding, are whistle showoffs. either on a stand or the locomotive sitting still itself. the harder but most realistic sounding ones are when the loco is moving, but not chugging, best example i can think of is this Video by @MyAmazingWorld at 1:14 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4snE-KAFpbE.htmlsi=i9cPijobyyHnadHl&t=74 as for chopping up the file itself, i might have to make a dedicated video at some point, its not very complicated, but there is a proper way of doing it to make it easier and less mind bending if you know what i mean. BTW, all the custom whistles and horns, as well as a few other sounds, Ive uploaded to a Github repository. I'm pretty sure i put a link on my channel in the community tab, ill double check and make sure its updated at some point
It was a luck find on ebay, was just another day looking for new locos to buy when i saw a pretty crummy picture on a listing, everything seemed legit, 'round $175 shipped, bit the bullet, came less than a week later, one elephant ear was broken off but super easy fix. Ive been keepin my eye out for another one since, but they sell like hot cakes when spotted, unfortunately its a luck of the draw right now, but tbh ive seen a fair number of BLI Niagaras for sale poppin up here and there. you might have more luck there tbh
