2-6-0 Steam Locomotives in France

Class 1587 (Locobase 21221)

Data

Locobase 11267 shows the 1586 class of 0-6-0s produced for the PO in 1886. In 1905, the PO's shops at Ivry converted seven to a Mogul wheel arrangement by adding a Bissel truck to lead the locomotive. Boiler pressure setting substantially reduced the firebox's area.

Class 1801 (Locobase 7412)

Data from Titre Exposition universelle internationale de 1889 a Paris. Rapports du jury internationale. Auteur - Volume France. Ministere du Commerce, de l'industrie. Picard, Alfred, ed. Volume Groupe VI - -Outillage et precedes des industries mecaniques. Electricite (5e partie) Classes 60 a 63. Rapport sur le materiel des chemins de fer; tables beginning on p. 183 ([] (accessed 1 September 2005).

Note the relatively small grate and deep firebox on this engine, which the Jury reported was intended for passenger service over steep, curvy lines. Ruling grades would vary between 2 and 2 1/2% and minimum curve radius measured 250 m. Over such a profile the locomotive was expected to pull 125 metric tons.

Class 1901,1622,1908,1933,1951,1961 (Locobase 21220)

Data from "130 n° 1 901 à 1 907 du PO" in the WikiPO at [], last accessed 12 November 2024. (Thanks to Alexander Blessing for his 15 October 2024 email noting the existence of the 1901 class, supplying details and the WikiPO link. Locobase suspected other Mogul classes would come from converted 030 classes and WikiPO )

Locobase 13210 describes the orginal 60-locomotive 882 class of all-adhesion, simple-expansion six-coupled goods locomotives that entered service in 1870-1873. In 1904, the PO contracted with Schneider et Cie for a "modification" of the original design. Instead, 922, 923, 929, 931, 933, 935, 936 reappeared as a clean-sheet septet in which the builder removed two simple cylinders and replaced them with a cross-compound pair. They fitted a substantially larger firebox and grate.

Inside the boiler, 214 smooth tubes gave way to 107 Serve internally finned tubes. Measured according to the nominal external diameters, tube heating surface area came to 96.47 sq m (1,038 sq ft). Taking the tubes' internal diameters, calculating that surface area and adding the area provided by the eight 3.175 mm (1/8") fins yields the figure shown in Locobase's specification.

Apparently satisfied with the 1901 upgrade, Ivry took thirteen of the 1529 class of 0-6-0s in 1905 to 1909, added 100 to each road number, and had Schneider apply the same changes to 1622-1623, 1632, 1636-1637, 1642, 1644, 1663 in 1905-1906. The PO added 1619, 1627, 1631, 1638, 1643 in 1908-1909.

At that point, Ivry converted another 25 882-class engines as follows:

1908-1918 from 910-911, 914-915, 918-920, 937-938, 940-941 in 1908-1910;

1933-1939 from 892, 900, 901-903, 905, 908;

1951-1955 from 882, 884, 887-888, 891; and

1961- 1962 from 855, 867 all in 1910
