bachmann 0-6-0 saddle tank switcher

[indian_hills_r_r]

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
