Hi everyone. Two quick questions: do MTH steam locomotives need an AC- connection through the drive wheels? I’m cosmetically modifying an MTH PRR D16 4-4-0 to represent a 1920’s-era D16b, and the final piece of the puzzle is to fit it with 68” drivers. I’ve found a set of the correct size, and although the tires are metal the wheel centers are hard plastic and thus not conductive. Will that cause problems? I’ve checked clearances and everything else should work. It’ll even fix the 1+ scale foot gap between the pilot and railhead!
Also, the banshee (freight) whistle in the sound file just bothers me. Is there a way to change the sound file to the prototypical PRR 3 chime? There's a sound file on the MTH page for this loco: http://mthtrains.com/content/20-3156-1. Is that just the same sound set it came with?
