SNCF's X 2400 are a French class of railcars.[1] The 79 XABDP 2400, unifiés 600 PS (440 kW) were built from 1951 to 1955. They were capable of carrying 12 passengers in 1st class and 56 in 2nd class,[2] they were 27 m (88 ft 7 in) long and capable of reaching a top speed of 120 km/h (75 mph). The railcars were often coupled to trailers of coupled to other units.
The class was put into service along the X 3800, Picasso. These 300 PS (220 kW) railcars facilitated the phasing out of steam traction and to renew aging railcar stock. The class was first allocated to Limoges and onto the lines of the Massif Central, coupled to XR 8000 trailers. The X 2400 was quickly accompanied by the X 2800 railcars, equipped with one engine only, but more powerful.
The maintenance cost of the X 2400 was greater than the one-engined X 2800 and so the class was moved to Rennes. The arrival of the X 2100 and X 2200 railcars precipitated the retirement of the X 2400, the last 2400 retiring in 1989.
The X 2464 was withdrawn from service in 1988 and was modified into a measurement train. It was painted into the Corail livery of dark grey, orange and white. Twelve railcars have been preserved.
Two sub-classes of X 2400 exist:
