To enable a railway vehicle to pass from a narrower track to a wider track and vice versa, the vehicle is provided with carrier, preferably flangeless, wheels which can roll without adaptation on either of the two tracks and with guide means having flanged members, e.g. flanged wheels, which can be made to engage the rails of either track in a change-over section where the two tracks meet, this section being preferably provided with means enabling the flanged members to be adapted automatically from one track to the other. |
