What is the smallest diameter turn I can use with the Bachmann HO 2-8-4 Berkshire Steam with tender?

Goofed again bought a engine at the big train show in Richmond Ca. Supposed to be a brand new unit never on the track. Took it home tried to run it nothing worked. Would not run with my NCE system. Do not know if it is the decoder or the engine so I am removing the decoder. What I need is the wiring for the dummy plug where the decoder would normally plug in. It is a Bachmann item # 50949 HO 2-8-4 Berkshire Steam Loco Tender [DCC]. Thanks for any help. Dick   

Am I reading the information correctly that the sounds only come through the cell phone or do the units have there own installed speaker?

Well this is pretty much my first experience with buying a new Bachmann engine and so far the experience has not been great I have had other Bachmann engines but they were always used with everything installed.
First thing I noticed is they do not come with a good instruction book as I have seen from other manufactures, second it states DCC ready and there is no instruction on how to connect a DCC system.  The Engine I bought is a 3 Truck Shay. Does any one have the instructions for installing the DCC system? They do have a few sheets of parts diagrams along with a CD that tells you some history and the lubrication method which is great. HELP

Just received a 55 Ton Three-Truck Shay brand new in unopened box. Question is, do these normally come with a instruction manual as there was none with mine. Is there a place to download them on the internet? 

Is there a repair manual available for the Bachmann 2-8-0 consolidation?

I lost the owners manuel and disc that came with my Two-Truck Heisler 1:20.3 Narrow Gage Steam Engine. Does any one know where I can obtain these? I think it somehow got thrown in the garbage when I took it out of the box. Thanks in advance for any help. I thought Bachmann was like other manufactures that had the manuels available on the internet but I could not find any.
