Astra Imperio

Astra Imperio is a tram produced by the Romanian company Astra Vagoane Călători in Arad. It is a 100% low-floor, designed in partnership with Siemens.[1][2] Imperio's design is based on the Avenio platform using electronic and traction equipment supplied by Siemens Mobility.[3][4] It is also available with local electronic and traction equipment supplied by ICPE-SAERP, using IVF 260FR inverters, along with SATREC and MBB31 control units; this variant, called Autentic, uses VEM DKABZ 0310-4 motors instead.[5]
