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 [ro], using IVF 260FR inverters, along with SATREC and MBB31 control units; this variant, called Autentic, uses VEM [de] DKABZ 0310-4 motors instead.[5]

The tram can be configured as a two to six-section vehicle, each section having a length of 9 m (30 ft), with a powered or unpowered bogie, depending on each operator's needs.[6] The first deliveries started in October 2014 for the Arad local transport company.[7]

Technical specifications

The longest tram delivered by Astra Vagoane Călători is the Imperio Metropolitan. These trams were ordered by the Bucharest City Hall administration on behalf of the Bucharest Transport Company (STB).
