These are two examples, one of which is a steam train on a Mexican   
   100-peso note, whilst the second is a SNIM train on a Mauritanian   
   5,000-ougiya note.

   I also know that the Canadian 10-dollar note, a polymer, has the image   
   of a train going through the Canadian Rockies. (The locomotive looks   
   like an F-40.)   
      
   Any other notable examples? What about images of undergrounds or trams?
