[[SNCF]]'s '''X 4900''' is a [[diesel multiple unit]] [[railroad car]] of the [[SNCF Class X 4300|Caravelle]] family.

They are derived from the two-car [[SNCF Class X 4630|X 4630]] [[diesel multiple unit|DMU]] with which they share the same Saurer {{Cvt|330|kW}} engines as well as their hydraulic gear box. The railcars possessed more power than the other Caravelles as they are formed of two motor coaches and one intermediate trailer, this authorised them to run at a top speed of {{Cvt|140|km/h}}.

Aesthetics are different from the other Caravelles as the painting scheme chosen is English blue, white and grey. Interiors were designed with care and benches ignored in favour of individual seats.

The class was first allocated at Marseille-Blancarde [[Motive power depot|engine shed]], this led to the replacement of the [[SNCF Class X 2400|X 2400]] and [[SNCF Class X 2800|X 2800]] in the region. Their superior power led to their allocation to passenger service duties on steep [[Grade (slope)|gradient]] routes in the Southern Alps. The other members of the class were allocated to [[Sotteville-lès-Rouen]] [[Motive power depot|engine shed]].

The 4900s in Normandy ran coupled to [[SNCF Class X 4500|X 4500]] and [[SNCF Class X 4750|X 4750]] around [[Caen]], [[Rouen]], and [[Le Mans]] and as far as [[Rennes]] and [[Tours]]. The Southern 4900s joined the Norman railcars upon the arrival of the [[SNCF Class BB 67400|BB 67400]] at [[Marseille]]. Despite the arrival in Normandy of the [[SNCF Class X 72500|X 72500]] and particularly of the [[SNCF Class X 73500|X 73500]], the 4900 have been taken out of service but in fact have kept to their regular schedule. The [[SNCF Class X 76500|X 76500]] delivered in 2004 will run between [[Caen]] and [[Rouen]] along the 4900s.<ref name="auto">{{cite web| url=http://www.train-rail.com/materiel/autorail/x_4900| title=4900s| access-date=2006-10-05| archive-url=https://web.archive.org/web/20070311203028/http://www.train-rail.com/materiel/autorail/x_4900/| archive-date=2007-03-11| url-status=dead}}{{full|date=January 2016}}</ref>

The three trains belonging to [[Basse-Normandie]] received an extensive servicing at the beginning of the 2000s and kept their original livery. The 10 trains belonging to [[Haute-Normandie]] received the ''TER'' as well as a modernised cab, identical to that of the [[SNCF Class X 4630|X 4630]] renovated DMUs. Thanks to their reliability, the X 4900 will be kept for another fifteen years, unlike the [[SNCF Class X 4300|X 4300]] and [[SNCF Class X 4500|X 4500]] which will be retired.<ref name="auto" />
