[#welcome] Lonney e,

Are you using an MTH transformer? Please don’t be using a Lionel CW-80 with any PS-2 locomotives.

My next guess is the circuit board that provides power to everything, not the sound board, has gone bad or has a loose connection somewhere or even a wirew is broken off. One thing to check real quick is the color dots on the engine and tender underneath, do the color dots match? If not you may have a mis-matched engine & tender.
