This is a list of town tramway systems in Spain by the autonomous community. It includes all tram systems, past and present. Cities with current operating systems, and those systems themselves, are indicated in bold and blue background colored rows. The use of the diamond (â¦) symbol indicates where there were (or are) two or more independent tram systems operating concurrently within a single metropolitan area. Those tram systems that operated on other than standard gauge track (where known) are indicated in the 'Notes' column.
