After the Nord had already had 100 km/h fast Crampton machines built with a driving wheel diameter of 2,100 mm from 1849, the Est procured similar ones with a diameter of 2,300 mm three years later. The engines of the Est could then even reach 120 km/h, which was beneficial to the Cramptons' reputation as “greyhounds of the rails”. To do this, the maximum speed allowed on the French railway lines had to be increased by decree of Napoleon III.
After the twelve examples numbered 79 to 90 had been delivered by Cail in 1852, another 15 by Schneider-Creusot with numbers 174 to 188 followed in 1855. The first carrying axle had a larger diameter than the second and carried a significantly higher weight. The locomotives could pull up to 15 of the passenger cars of their time and usually reached an average speed of 55 to 75 km/h with nine to ten cars.
Since the adhesive weight of just over ten tonnes later turned out to be insufficient, as with most Cramptons, a rebuild took place from 1881. In order to shift the weight further to the rear, particularly massive and heavy wheel hubs and a smaller boiler were installed. To compensate, the boiler was now operated at a higher pressure. Together with other additions, such as the Westinghouse air brake, the adhesive weight could be increased by about 3.5 tonnes.
It was not until just before the turn of the century that other express locomotives were able to overtake the Cramptons. Number 80 “Le Continent” is the only example that has survived to this day. It was restored to its original condition in 1925 and initially exhibited at the Gare de l'Est in Paris. In 1946 it was made operational again, but has been standing since 1970. Today you can find the theoretically operational machine in the Cité du train in Mulhouse, but no renewed refurbishment is currently planned.
