Description
A flexible small-capacity rail vehicle for routes where passenger flows are relatively low but a high quality travel experience is desired. Available in high floor configuration suitable for level access from standard height railway platforms, or low floor configuration suited to tramway use. Flexible external appearance and internal layout. Traction power derived from small automotive internal combustion engine for longer routes or from intermittent electric supply, requiring contact with power source at stopping points only (where stops are close together and zero emission operation is required).
