Alstom says Ixege is the first bogie to combine the ability to rotate with a low-floor. This is achieved by having a very flat underfloor primary suspension which is only 450mm above the rail, and by using a permanent magnet motor which is small enough to be installed outside the bogie frame. Ixege is designed to filter wheel-rail contact vibrations. Ixege also enables LRVs to be designed which a wider low-floor area.
