My grandson got flim-flamed by a salesman into buying a B'man SD40-2 engine (item 67017).  He was led into believing the engine was equipped for DCC and had sounds.  He has been into MTH O gauge for 4 years and I and comfortable with their technology.  I have been trying to decipher what he needs to build a very small layout for under the Christmas tree.  I bought a complete EZ Track layout and have ordered the B'Man Command Controller System.

My question is what will this diesel need to run on this layout under DCC?  Is a second option needed for sound or is there a combo kit that will give DCC & sound?

Thanks for any/all advice from a real neophyte to HO & DCC.
