Said drive arrangement comprises a motor device for driving said drive wheel member, a transmission device for transferring torque from said motor device to said drive wheel member and a brake arrangement for braking the drive wheel member. Said drive arrangement is configured to be coaxially arranged relative to a centre axis of said drive wheel member. A bearing configuration is arranged in said track support beam, said drive arrangement configured to be journaled in bearings to said bearing configuration for allowing rotation of said drive wheel member relative to said track support beam and for supporting said drive arrangement.
