The order comprises 19 trains for domestic regional services and six trains for cross-border operation into the Italian autonomous province of Alto Adige.
The trains are being ordered under a framework contract for up to 300 Talent 3 sets, which was awarded to Bombardier in 2016. This included an initial order for 21 trains for Vorarlberg.
Last year the government of Tyrol awarded ÖBB a contract to operate regional services in the province for 10 years from December 2019, a deal which includes the provision of new rolling stock.
Delivery of the new trains is due to begin in 2020.
