Stadler had previously been selected as the preferred bidder for the SFr 45m ($US 44.5m) contract in November 2016.

The trams for Ostrava will be assembled at Stadler’s plant in Prague, which will work closely with Czech suppliers. The first vehicle is due to be completed in March 2018.

The 2-section unidirectional trams will be 24.9m long and be able to carry up to 188 passengers, including 61 seated. The trams have wide doors and a wheelchair ramp for efficient boarding. They will be fully air-conditioned with a maximum speed of 80km/h.
