The Est 0.250 to 0.500 and 0.701 to 0.766 were 0-6-0 locomotives for freight traffic of the Chemins de fer de l'Est. They were first put in service in 1859 and retired from service from 1892 until 1937.

Construction history

The first series of machines was built 1858-1862 by Schneider-Creusot for the Compagnie des chemins de fer des Ardennes [fr], which later merged with the Chemins de fer de l'Est in 1863. The series then received the numbers Est 0.300-0.350.

Already in 1859 the design had been adopted by the Chemins de fer de l'Est, which had the type built from 1859 to 1884 without significant changes by their own workshops as well as various other manufacturers as series Est 0.250-0299 and 0.350-0.478.

In 1881-1882 the locomotives Est 0.479-0.500 as well as 0.701-0.708, and in 1883-1884 the 0.709-0.766 were put into service. Due to their longer fireboxes these later machines had an increased power output. The firegrate area had been increased from 1.35 m (14.5 sq ft) to 1.63 m (17.5 sq ft). The new boiler had a boiler pressure of 9 kg/cm (0.883 MPa; 128 psi) and the machine's adhesive weight increased to 36.6 t (80,700 lb), while tractive effort was 5,329 kg (11,700 lb).

From 1904 to 1909 forty-eight of the machines from series 0.252-0.428 were rebuilt as 2-6-0 two-cylinder compound locomotives. These 48 machines were renumbered as Est 30.252 to 30.428 [fr], retaining their original numbers with an additional prefix of '3' as follows:

From 1906 to 1926 ninety-two of the machines from series 0.254-0.489 and 0.701-0.766 were rebuilt as 2-6-0 locomotives with simple expansion. The 92 machines were renumbered as Est 30.254 to 30.766 [fr], retaining their original numbers with an additional prefix of '3' as follows:
