Encyclopedia
The SNCF
Class X 72500 diesel multiple unit
s were built by Alstom
between 1997 and 2002. They operate longer distance TER
services, particularly in the areas south and west of Paris
, the Paris to Laon line, around Tours
, Nantes
, Toulouse
, Lyon
, Dijon
, Nevers
, Grenoble
, Bordeaux
and the South Coast of France. They do not operate in the far north of France.
The X 72500 units come in two types:
Three sets can be coupled where required
The maximum speed is 160 kilometres per hour (99.4 mph).
Units are equipped with two MAN
six-cylinder engines of 300 kW per motor vehicle. Each train has four engines for traction, giving a total power of 1200 kW. The engines drive a hydromechanical Voith
transmission.
Additionally each vehicle also includes a 135 kW Perkins
/Mecalte diesel generator
for auxiliaries (lighting, air conditioning, door controls, etc..). The braking system is provided by mechanical disc brakes coupled to a hydrodynamic engine brake.
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.
