The X 2700 series was a twin-engine diesel multiple unit operated by the French state railway SNCF . With the single-engine series X 2720 (RGP1) it counted as RGP2 to the "Rames à grand parcours" (RGP) called long-distance railcars for long-distance traffic.

Paul Arzens was responsible for the design .

history

In 1954 and 1955, the series comprising 20 railcars (road numbers X 2701 to X 2720) with the associated control cars (XR 7701 to XR 7720) were delivered to the SNCF. The railcar was twin-engine, a reliable powerful diesel engine for a single-engine version was not yet available. As from 1955, thanks to the SACM MGO V 12 SH engine, a corresponding single-engine railcar ( X 2720 series) was ready for series production, the construction of the X 2700 was discontinued.

The trains, which initially only had 1st  class and had a kitchen in the control car, were converted into two-class units without a kitchen compartment from 1972 onwards. The total number of seats rose from 104 to 113. With the delivery of the RTG turbotrains , the X 2700s were pushed into regional traffic around Bordeaux and Limoges from 1973 onwards . Some long-distance connections were left to them for the time being: Bordeaux - Rennes (until summer 1973), Saint-Germain-des-Fossés - Saint-Étienne - Le Puy-en-Velay (until autumn 1975) and Bordeaux - Clermont-Ferrand - Lyon (until the end of 1978 ).

Due to the high maintenance costs, especially because of the double engine, the X 2700, like its sister series X 2400 , were gradually shut down in the period 1980 to 1986. In 1984, the X 2707 and X 2714 motor coaches were converted into the X 2700 double motor coach for track inspections using ultrasound . The vehicle, which was used until 2010, received additional headlights, a partially modified window layout and a different paintwork.

From the X 2700 series, the X 2716 (at the Train Touristique de Puisaye-Forterreund ) and X 2719 (at the Matériel Ferroviaire et patrimoine National (MFPN)) have been preserved. X 2709 is a non-motorized dining car at the Chemin de Fer du Haut Forez .

The railcars were powered by two Renault V-12 diesel engines (type 517 GV 12) each with 221 kW of power, one behind the driver's cab and the other in front of the transition to the control car. The power transmission to the axles was mechanical . The maximum speed of the vehicles - also with the X 2720 and X 2770 series - which can be used in multiple traction was 124 km / h. The railcar weighed 45 t, the control car weighed 32 t, and both vehicles were together 52.16 m long. The trains were originally painted light green, cream-colored and gray, which earned them the nickname "Lézards verts" (green lizards). A silver-colored decorative strip made of metal ran underneath the ribbon of windows, which was replaced by a light colored strip when it was repainted. The round SNCF emblem on the front of the railcar gave way to a more modern-looking lettering. Nine units (X 2701–2704, 2706, 2710–11, 2715 and 2718) were adapted to the livery of the RTG and RGP1 ​​in the 1970s and overmoulded in the colors sun yellow and gray.
