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]
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June 2021: The trainsets delivered to Flytoget were withdrawn from service after 19 days of operation due to discovery of cracks in the chassis.[13] In January 2023, the trainsets resumed operation.[14][15]
