The invention concerns a rail cycle (10) that includes a frame (12) that supports a rotating front wheel (14) and a rear wheel (16) that are intended to be in contact with one rail (17) of a railway track, where the rail cycle (10) also includes an extra support wheel (32) arranged to rotate at one end of a supporting arm (30) that at its other end is articulately attached to the rail cycle's (10) frame (12), where the extra wheel (32) is intended to be in contact with the other rail (34) of the said railway. With known rail cycle guiding devices that are located directly alongside the cycle's front and rear wheels on one of the rails, it is not possible to arrange the guiding device in a non-working position in those cases when the rail cycle is to be used as a conventional cycle. The rail cycle according to the present invention is distinguished in that the guiding plates (56, 58) are attached in a removable manner to the rim (48) of the respective wheels (14, 16) and that, when fitted, extend in a radial direction beyond the outer periphery of the wheel (14, 16). |
