BKK now has until March 18, 2023 to decide on calling down the option to buy the trams at 2014 prices. The option does not stipulate tram type, allowing BKK to buy long or short trams.

The municipal council of Budapest voted unanimously in October to call down an option for 20 trams, with a value of around HUF 17 billion, included in the contract the city's public transport company signed with CAF in 2014.
