So far two single commuter train units tested in daily passenger use (direct replacement of a Diesel powered train) for 18 months in Germany, 3 months in the Netherlands, now in Austria. Some sources say with cost advantage over Diesel trains right now. Will it be there long term? I do not know. But cumulative orders of to my knowledge 60+ trains can be something. Edit: two, not one unit
