One of the really neat features of MTH's DCS and PS2 locomotives is the ability to change the personality file that's located in each PS2 locomotive. If MTH issues a revised or updated file, you can make the changes simply by changing the file. If you're doing an upgrade to PS2 and had to use a "similar" file, you can change it when a more appropriate one becomes available. That's recently happened with the Premier model of the N&W Class A (2-6-6-4) articulated steam locomotive. When I did the upgrade to PS2, there was no PS2 Class A available and hence there was no personality file, so I use the one for my MTH Premier N&W Y6b. MTH recently issued a new, enhanced PS2 Class A, so I was able to download that sound file and upload it into the locomotive. The new whistle is much more appropriate and is a good match for that heard in recordings made of prototype Class A locomotives when those giants roamed the rails. The other sounds are more appropriate as well. The video is available in the usual three formats (Windows Media, Real Media, and MPEG-4) on the Multimedia page of the web site. Here it is, in reduced resolution and quality, on YouTube.
