A watertight housing provided with continuous magnetic tracks at opposing lateral sides of said housing. At least one drive motor in the housing operably connected to at least one continuous magnetic track for driving the continuous magnetic tracks. The housing being provided with a main side between the continuous magnetic tracks.

A track system for traction of a vehicle that is connectable to an axle of the vehicle and includes a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track-engaging assembly includes a drive wheel for driving the track, idler wheels for contacting a bottom run of the track, and a bogie carrying the idler wheels. The track system includes a transmission for transmitting power from the axle of the vehicle to the drive wheel such that a rotational speed of the drive wheel is different from a rotational speed of the axle of the vehicle. The track system includes a connector disposed between the transmission and the bogie such that the bogie is movable (e.g., pivotable) relative to the transmission. The connector may be disposed below an output shaft of the transmission.
