All new 18 FLIRT 3 vehicles from Stadler for the end customer Srbija Voz are in full service starting this year. These FLIRT 3 trains are equipped with an older version of the ATP system RAS 8385 I. The decision to equip the additional 18 FLIRT 3 vehicles with the ATP system RAS 8385 I was based on the results of the previous project where the same FLIRT 3 vehicles were equipped with the same system and provided a strong reference and because of a long-term partnership with STADLER and end customer Srbija voz.
