smart has created a unique forfour – nicknaming it the ‘forrail’– for a one-off test. smart officials describe the regular fourfour as the 'ultimate commuting machine' but also admit that the train does has the more direct, point-to-point advantage, so in an effort to combine the best of both worlds, the city car was fitted with solid steel 22-inch wheels built specially for the railway track. To avoid any steering movement, supports were welded in place, before the smart forrail successfully ran for 10 miles along the privately operated Bluebell Railway, much to the surprise of local trainspotters!
