It took six months of clever CAD modelling and engineering work to convert the Smart ForFour in to a miniature train. The changes were carried out by train engineers Interfleet who usually work on 16-litre, 70-tonne diesel locomotives, and had to find an entirely new approach for the 999cc, one-tonne Smart.
Taking to the track at the privately operated Bluebell Railway, the Smart Forrail was a resounding success. The newest addition to Smart family completed its 10-mile trip through Sussex with ease - much to the bemusement of onlooking commuters.
Thanks to the strong, safe Tridion cell of the Smart ForFour, the experiment overcame challenging engineering obstacles and stuck to the track like glue. The Forrail combined the best of rail travel with the efficient and fun nature of the Smart to create the perfect commuter transport.
Shortly after, the Smart was converted back in to its road-going alter ego. Not that that's an issue, as the Smart can drive from London to Aberdeen non-stop for as little as £39, and offers plenty of comfort for up to four occupants. For many drivers, it still is the ultimate commuting machine.
