Oaris is a modularhigh-speed train platform developed by the Spanish manufacturerCAF.^[3]

Oaris is a non-articulatedelectric multiple unit withdistributed traction, enabling 4-car, 6-car and 8-car configurations.^[3] Each car has one poweredbogie, with electric motors on bothwheelsets, and one unpowered bogie.^[4] Power equipment is designed to enable adaptation to all four of the mainoverhead electrification systems in use across Europe. For the train, running gear with1,435 mm (4 ft 8+1⁄2 in) (standard gauge),1,668 mm (5 ft 5+21⁄32 in) (Iberian gauge) andvariable gauge options has been developed.^[4]

Oaris bodyshells are manufactured from aluminium.^[3] The driving end cars are 26,780 mm (87 ft 10 in) long, middle cars 24,780 mm (81 ft 4 in), and an 8-car set measures 202.24 m (663 ft 6 in).

The train is fitted with 660 kW (890 hp)motors, giving a total power of 5,280 kW (7,080 hp) in the 4-car, 7,920 kW (10,620 hp) in the 6-car, and 10,560 kW (14,160 hp) in the 8-car configuration. Design speed is 350 km/h (220 mph), the service top speed is 320 km/h (200 mph).

• May 2010. After fours years of development in a project supported byCDTI, CAF announced the Oaris platform with the unveiling of a full-scale mock-up in May 2010 in the International Rail Forum 2010 atValencia.^[3]
• September 2010. A prototype starts to be assembled byCAF.^[5] It has 4 cars and is designed for 216 seats.Renfe has reserved the class 105 for the prototype.^[4]
• January 14, 2011. CAF announces that the prototype is finished and will undergo dynamic tests in early 2011.^[6]
• December 2011. Four-car prototype undergoes trials at up to 352 km/h on the Madrid to Sevilla route.^[4]
• Spring 2013. Prototype gets homologation by Brazilian Rail Industry Association (ABIFER), which will allow CAF to offer trains for the proposedhigh-speed rail connection between Rio de Janeiro and São Paulo.^[7]
• 2013. Test runs for homologation in Spain. In October 2013 company sources said the approval process of Oaris is in the final stages and within months is ready for operation.^[8]
• March 2015: The Norwegian airport train operatorFlytoget ordered eight 4-car trainsets (maximum speed 250 km/h) to supplement their 16 trains fleet on theirDrammen-Oslo-Gardermoen Airport service and will be allowed to run at a maximum speed of 210 km/h on the line, starting from June 2021.^[9][1] They will be known as Class 78.^[10][11]
• June 2019: Belonging to the five train manufacturers selected to tender forHigh Speed 2 rolling stock CAF presented their Oaris trains as passenger trains for HS2.^[12]
• June 2021: The trainsets delivered toFlytoget were withdrawn from service after 19 days of operation due to discovery of cracks in the chassis.^[13] In January 2023, the trainsets resumed operation.^[14][15]
