Just because the motor is DC and the locomotive electronics rectifies the track power for that DC motor as stated above, that does not mean ALL components on the locomotive are designed and/or unharmed by DC track power. AC has been the 3 rail  O gauge convention for over a century.

Second, TMCC & Legacy command control signals REQUIRE AC track power and in some cases can be damaged by DC.

Like @gunrunnerjohn said:

Lionel specifically specifies AC, and not all Legacy will run properly on DC.  The risk is yours.

Go ahead and risk your expensive components for what reason? Just because the locomotive moves under DC in a test of yours, that does not mean the Legacy transceiver components in the locomotive are unharmed.

As @superwarp1 stated, the motors are already getting DC anyways, so just follow the AC standard.
