Resistor or diode or other?

Hi All,  first thought is that we have mod guide thread and mod gallery, we should have a dedicated repair thread or a dedicated 'what is this?' thread.

Anyhow, on to my issue.  I bought a broken monorail ("monorail advice" if youre interested https://www.blueplastictracks.com/showth...p?tid=3285).

I tore it apart and tested everything and I have isolated it to this little bugger not working.  if I bypass this, the thing seems to work just fine... but one assumes they put this there for a reason, huh?
      

Everyone is telling me that its a resistor, which was my first thought.  The only problem is that it clearly only has 2 bands; the pics might have a reflection making it look like more.  its clearly 2 brown bands.  When I search online I cant find anything that references resistors with 2 bands.  everything I have read says 3 or more.  

Does anyone have any experience with this or suggestions?

Thanks!
