Lionel Legacy locomotives feature 24 levels of smoke control, providing precise, realistic smoke effects for steam and diesel model trains. To operate these smoke functions, Legacy locomotives require a dedicated AC regulator, which controls the locomotive’s smoke unit heating element.
These AC regulators for Lionel Legacy locomotives are designed for Legacy electronics and are not compatible with TMCC 1 locomotives, ensuring safe, reliable smoke-system operation. For collectors and hobbyists, using the correct Legacy AC regulator is essential for optimal smoke performance and longevity of your Lionel train.
