legacy controller vs. MTH DCS

will legacy control mth protosound equipped engines?

Legacy DCC you mean? I have an NCE PHP system and it runs my MTH loco with protosound 3.0 just fine.

Are we talking O scale here? I would post this question on the Classic Toy Trains section of the forum, you will find a bunch of Legacy users there.

Thank you but, I don’t know what NCE PHP is

It is an NCE DCC system, but don’t worry about it. I am fairly sure you are asking about using the MTH DCS compared to the Lionel Legacy control system? If this is the case, as I wrote before, post this question on the Classic Toy Trains section of the forum.

Thank you I will…
