The driving position, TGV type centered in the cab, was designed to facilitate the work of the driver. It also includes elements to enable Driver Only Operation (but the absence of CCTV/mirrors require a second crew member on board) and the ATESS system, a data recorder way more advanced than those fitted to previous stock. The overall management of the equipment is insured by an onboard computer system. Failures can be quickly diagnosed by it. Check levels of oil, fuel and coolant are the same computer.
Phase reliability of these railcars has also been particularly long, which earned them a bad reputation even today. Two back operations at the factory took place:
Retrofit 1, 1998 to mid- 1999, aimed to security changes and installing new versions of the onboard computer system;
Retrofit 2, from mid- 1999 to late 2000, where more than 200 modifications were made, mainly at the level of passenger comfort.
In 2006, recurrent problems still existed at the level of generators and devices for opening and closing doors.
