I just acquired a bachmann diesel engine and I'm trying to find out what exactly IO have.   Is there a place I can go to find out about it?  It's a Union Pacific engine that has a number 9202 under the window.  It also has a card decoder inside tagged "N860X-P02B.  I'm pretty new at this and I know just enough to know what I don't know.  Any help would be appreciated.  I did not get a box with it.
thx
Ken
