Thank you for the response.  I found that I had not secured the pin properly.  One of the pins was bent slightly.   After gently straightening that problem it runs fine.   I appreciate your response.

Got this (bachmann item 80101 as a gift.  It is DCC ready (equipped) and printed insert within the box says it  is 100  per cent backwards-compatible with Standard DC.  BE SURE TO READ THE MANUFACTURERE'S PROGRAMMING INSTRUCTIONS.   There are no instructions in the package.  Where can I find them?   I have a DC layout.   I connected the plugs from the tender to the loco and inserted the loco's pin into the tender's device.  Headlight  comes on with power from MRC 1200 DC power pack, but no movement.   WHERE can I find "programming instructions?   Seems like this locomotive should run on a DC layout.   Am I missing something here?   Do I have to remove pins from the tender?  Insert "dummy plugs?"   (I Checked all FAQ and ran a search but could not find a responsive thread.)
