Scales Modeled: HO mainly, N, S, O, G
Legacy sounds like it does what DCC does. Controlled volts to the motor and full track power to lights and smoke unit.
I have DCC for my HO and N trains.

Scales Modeled: S gauge
Both are digital control systems that work with full voltage on the track. DCC has smaller decoders and offers much more programmability and a larger choice of sounds. It is an open system. Many S scale operators use it.
Legacy is much simpler to set up and does not use the track to communicate with the engines. It is proprietary to Lionel and has the complementary Layout Control System for iPads. It excels at high current demands. If an engine needs 5A for all its motors, smoke units and light/sound, no problem. If a layout needs 100A to the track, no problem. My layout has power to supply 60A to the track (max 10A to a single Power District) but the most I ever saw so far in an operating session was a little under 20A.

I got a lot of noise with a 30:1 dc motor so I thought that it must be too much play with the gears and axles. I ordered a standard dc motor and the is far less noise. However, I still think that there is too much axle play. But, I am not going to do any thing about it. That is why I bought a second 312.

Sell it and get another 312, maybe a Hudson, or a Northern.
