Oil car

I was trying to come up with something that was repurposed for MM but couldn't find anything.  So I went down to the base and the tracks to just take some shots .   I took one of the biggest destroyer( couldn't find a # on it) and then couldn't make up my mind on which to blip!  the other that was in was the USS Sampson a guided missile destroyer. 
   so this is my Mono Monday shot but not on challenge.  Thanks to Apollofly for hosting!!
