Cab Forwards were designed to keep the crews from getting asfixiated from smoke while long tunnels. While a few other railroads considered purchasing the design, only the Southern Pacific Railroad ever bought any. Many wheel arrangements were used but most of them were of the 4-8-8-2 design.
Many Cab Forwards also contained a Seperate Air Horn. This Sound Profile also contains the ability to play this horn sound using Function 12. (remappable if desired)
AC-6 through AC-12 Cab Forwards Used a Saturated airpump mounted on the front of the boiler. These had a very distinct sound which we have gone through great lengths to duplicate.
As with all LokSound Select Steam Files there are 16 available whistles, which can be changed using CV 48
