Smart forrail Concept
British train engineering specialists at Interfleet have developed one-off Smart ForFour modified to run on rails. Nicknamed the Smart forrail, the prototype is aa fully certified mini-train. The smarts tridion safety cell allows it immense strength, which underpins the forrail. No matter how simple Roger Moore made it look in his Mercedes-Benz 250 SE, removing the tyres and placing it on tracks isnt really possible in real life the car would fall off almost immediately.
