The 35m-long bi-directional vehicle will initially be sent to the company's test centre at Wildenrath in Germany for dynamic tests, before being delivered to The Hague for acceptance testing this summer.

HTM placed an initial €100m order for 40 Avenios with Siemens in November 2011, and exercised a €55m option earlier this month for 20 additional vehicles.

The 40 trams under the main contract will be deployed on Lines 9, 11, 15 and 17. Vehicles from the second batch will be used on Line 1.
