I am looking into the purchase of Bachmann DCC equipped 2-10-4 and 4-8-4 item #'s 50803 and 51202 and I have some questions about these
1) What type of DCC decoder are these equipped with and is this something that could be changed to a Sound Trax, Digitrax or other decoder
2) Is there a spec sheet on these locomotives giving some more details to aid in my choice to purchase or not
3) I have heard that there were some running and performance problems with  some  Bachmann models are these recent models in which the problems have been resolved
