Oaris is a modular high-speed train platform developed by the Spanish manufacturer CAF. ^[3]

Technical details

Oaris is a non-articulated electric multiple unit with distributed traction, enabling 4-car, 6-car and 8-car configurations. ^[3] Each car has one powered bogie, with electric motors on both wheelsets, and one unpowered bogie. ^[4] Power equipment is designed to enable adaptation to all four of the main overhead electrification systems in use across Europe. For the train, running gear with 1,435 mm (4 ft 8+1⁄2 in) (standard gauge), 1,668 mm (5 ft 5+21⁄32 in) (Iberian gauge) and variable 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).

History

• May 2010. After fours years of development in a project supported by CDTI, CAF announced the Oaris platform with the unveiling of a full-scale mock-up in May 2010 in the International Rail Forum 2010 at Valencia. ^[3]
• September 2010. A prototype starts to be assembled by CAF. ^[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 proposed high-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 operator Flytoget ordered eight 4-car trainsets (maximum speed 250 km/h) to supplement their 16 trains fleet on their Drammen-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 for High Speed 2 rolling stock CAF presented their Oaris trains as passenger trains for HS2. ^[12]
• June 2021: The trainsets delivered to Flytoget 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]}
