Those sets are built by CAF and Alstom. Thanks to the BRAVA gauge-changing system developed by CAF, these units will run on Mainline services combining HSLs (1435mm-4ft8in) with conventional lines (1668mm-5ft6in). These will probably branded "Altaria".
They will have a top speed of 250kph-157mph under 25kV-50Hz AC and 220kph-136mph under 3kV DC. Unlike TRD 598s, they will be devoid of the SIBI tilting-system of CAF.
The livery seems to be a compromise between the applications of the "Grandes Lineas" livery to brand-new Talgo 7 and refurbished Talgo 4 stock.
One can notice the single, central vestibule.
