Thanks guys.

Yes, that is the cord.  The shop I bought it from didn't have a spare on Christmas Eve but luckily "Santa" had a power supply from an old N set from when he was a kid, which saved Christmas morning.

The shop owner offered to get me one or install a "phono jack" on the end of the one that I have.

Thank you all for your help. 

I bought a Bachmann Spectrum set "used" from a local train shop. Very nice set.  The only thing missing is the cord from the power pack to the track.  It appears to need a plug on one end (not terminals like I am used to).  Can I buy this power cord?  I checked into a replacement rerailer/power connection track and that one has terminals on the wires and not the plug.  Can I just get that plug from Radio Shack?  Any help would be appreciated.  Thanks.
