Hot Water posted:The "first run" of the SP cab forwards, was, as best as I can remember, a JLC version with only 2-chufs per revolution and an incorrect whistle. I purchased one, that was discounted, in an un-opened box, then sent it Train America Studios for up-grade to 4-chuffs per revolution and a more appropriate SP style whistle. It still runs great!
The newer/latest Vision Line cab forward, has Legacy sound and special features, plus was available in different road numbers, as well as a "Daylight painted" version (obviously fantasy). Cost a LOT more money too!
Hot Water, can the whistle still be upgraded? On older model TMCC models it could be done by changing out an IC.
