My Nathan Airchime 2nd generation Old Cast P3R2, formerly off of a Southern Pacific 6 axle Alco, mounted on Wilmington & Western (B&O) SW-1 #8408 during a Santa Claus Express
I must agree Steve you got an awesome sounding horn there on 8408. I kinda wish that could stay on the locomotive for one whole year and then the following year switch to another horn of your choice. Merry Christmas to you.
WOW that sounds A LOT like a M3. You can really hear that the old cast P3 was designed as an air and maintenance efficient M3. Gotta respect M3s and P3s (especially old cast)
