The network was expected to be expanded with a second and third line but the project was cancelled but plans to recover it are being made.

The network was expanding quickly in a radial form across the city, with the present Spain square as the center.

[2]: 41 On 10 June 2009, the Traza consortium of Tuzsa, CAF, FCC Construcción, Acciona, Ibercaja and Concessia selected to build new tramway.

A second line is planned, utilising existing Cercanías Zaragoza track for tram train operation to Villanueva de Gállego.
