Spain, Stadler Citylink:
The Citylink is a tram-train manufactured by Stadler Rail Valencia (formerly Vossloh España) which is designed to operate on both tramways and mainline railways. It features pivoting bogies (for less wear on the tracks than conventional fixed tram bogies) and is available in either a bidirectional version or unidirectional version. This drawing shows a generic bidirectional Citylink tram-train.
