OK...update...The locomotive operates in MTS only! I had it tested on an MTS layout. The Phoenix Sound is programmed to the proper MTS buttons. It WILL NOT go at all in DC. So, either I'm going to have to.invest in an MTS system or something that will hopefully operate DCC and MTS And operate the whistles etc. There are no reed switches or magnets all sounds are done by remote. Still highly confused but at least I know.It operates! And it is very impressive!
