{ Requested by @BNSF_Fan } CSX SD50 #8542, it's RS5T being mostly known for being the King of all Train horn and has been that way for years, but sadly this unit now lays in the Waycross, GA dead lines. This unit is EX Seaboard system SD50 and started out in the 80's with a K5LA and some how go a RS5T (Space, H and F are for the horn)
If you would like to use this horn Lever or the horns please give me credit!
