I have a spectrum ho 0-6-0 switcher brand new. it says its dcc ready but when I opened it up to install a decoder there was no 8 pin receiver board. there is a pcb board there with numbers on it. am I to assume that even tho it says dcc ready that I will have to solder the decoder in permanently.   also I noticed Bachmann has exploded views of it trains for parts viewing, do they have manuals that tell a person how to open the engines up? took me 30 mins to figure out how to get the body off.  thanks 

I just purchased a ge 70 ton loco  Bachmann item# 60604. it says dcc on board. is there anything I need to do to use it with my mrc prodigy A squared dcc controller other than put in a decoder. this unit will also be used on a dcc layout that uses nce dcc controller.
