The model originally did not come with DCC and Sound, so I added an ESU LokSound Select Micro to the Tender. A sugar cube style speaker in a 3D printed enclosure is installed in the Tender. The front headlight has been replaced with a Surface Mount LED and is functional. The rear tender light is replaced with an LED and it is functional.The Engine and Tender are hardwired together, so the it no longer fits in the original box. The original box is also included.
