The company was founded by Crochat in Paris in 1899 . Between 1908 and 1918, 420 locomotives for narrow-gauge and regular- gauge railways were built near Crochat . At times the company also manufactured road vehicles with petroleum- electric drives. In 1924 the Crochat patents were acquired by the Société anonyme des Établissements Decauville Aîné , two years later Crochat founded the Société Auxiliaire d'Entreprise (SAE). In 1926 the company filed for bankruptcy .

130 machines were N-type 22 L 2 to the French Ministry of War, 38 of the Railway Company du Nord Compagnie des chemins de fer (NORD) delivered and 2 to the Compagnie du Gaz de Paris. The two-axle petroleum-electric locomotives for the 1435 mm gauge ("standard gauge") weighed 22 t and had a central driver's cab .

Larger was the petroleum-electric type 44 L 4 N, which rested on two bogies . It was 12,900 mm long, had an empty weight of 44 t, an output of approx. 200  hp and a top speed of 25 km / h. In 1916/17 90 copies of him went to the War Ministry and 40 to NORD.

The 14 L 4 60 series for a track width of 600 mm had an 80 HP petrol engine that powered the electric motors via a generator . The locomotives had two two-axle bogies and a central driver's cab; they were built according to Crochat's designs at the Compagnie des forges et aciéries de la marine et d'Homécourt in Saint-Chamond . The War Department ordered 200 of these machines, which were delivered in 1918. Five such locomotives went to the Compagnie du chemin de fer du Maroc oriental (CMO) and ten to the Collet company in Rabat ( Morocco ). Furthermore, Crochat manufactured locomotives for this gauge with an end driver's cab, some as pit locomotives with low cabs. Three two-axle battery locomotives were delivered to the Peugeot establishments .

In 1918, Crochat built 19 locomotives for the Compagnie des Salins du Midi for the 500 mm gauge. The locomotives had a central driver's cab and two three-axle bogies. In the early 1920s , two-axle standard gauge locomotives powered by accumulators were developed as type 12 A 2 N for smelting works .

The SAE also put a meter-gauge type on the rails in 1927 . The two-axle locomotive with an end driver's cab had an 80 HP internal combustion engine from MAN , which was coupled with a 60 kW generator. The latter supplied the electricity for a 30 kW electric motor per axle.

The Chemins de fer du Calvados and other companies received short, two-axle rail buses for the 600 mm gauge from Crochat in the early 1920s . The short vehicles were two-axle and had a petroleum-electric drive.
