As of a couple of years ago Lionel started selling Legacy components outright. Keep in mind there are three main forms of Legacy. Early Legacy starting around 2008 used what appears to be TMCC boards but programmed for 9 bit code. Later they introduced the RCMC with greater capabilties like multiple smoke units. In the past few years they used an updated form of the back EMF system first introduced by ERR. The advantage of the last system is it doesn't require an tach sensor on the motor. The bad news is they won't run in lock step with other Legacy engines.

RCMCs are able to be programmed for each engine's driver diameter and gear ratio. Thats what enables them to be run MU. The bad news if you order RCMCs with the intent to run with other Legacy it will be only luck that that engine will match the board you selected.
