My brand new old P2K BNSF GP60s taken to the DCC tracks for the first time since having sound decoders installed. I used a MRC mini sheer brilliance decoder in each. Had to do some milling to get the speakers to fit. These two helper units will be ran together at all times so I installed the speakers on the opposite sides (ie. the lead unit has the speaker on the left and the trailing unit has the speaker on the right).
