Hello, thinking ahead to future releases of steam trains for TSW (none announced yet, but hoping!) Please include the ability to quill, or 'play,' steam whistles, rather than having them just be on/off like in TS20xx and Microsoft Train Simulator. The sound of steam whistles sounding different pitches is one of the most evocative elements of railfanning, and many engineers historically took great pride in unique, personally-identifiable ways to control the pitch of the whistles. Unfortunately, to date, almost every simulated steam engine only lets you turn the whistle on and off. This is unrealistic and really misses one of the most thrilling parts of experiencing a steam engine in person. For any forthcoming steam engine releases, it'd be great if the player can control the pitch of the whistle by using the scroll wheel of their mouse, or any other means to replicate the incredible variability of blowing a steam whistle. Please do not release steam engines with just on/off whistle control - real world steam whistles are the voice and soul of steam engines, so please give them the personality they deserve! Thank you for your time in reading this.
