Orleans 0-8-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 1101 (Locobase 11272)

Data from "040 nñ 901 a 913 puis 1 101 a 1 113 du PO" in the Wiki PO at [link], last accessed 19 April 2022. See also Eric Verdebout, "Les locomotives 040 a tender separe au XIXe siecle". Rails d'Autrefois nñ 2 novembre 2010) on the Circle Historique du Rail Francais (CHRF) website at

[link], last accessed 24 April 2022. Cail works numbers were 1134-1146 in 1863, 1947-1961(road numbers 1149-1163) in 1877

Designed by Camille Polonceau and introduced in sizable numbers, the Orleans eight-coupled freight engines had an unusual running gear layout that placed the eccentrics and their extensions outside the drivers. They were driven directly by the outside cylinders, which were served by valve chests placed on top.

This set had one drum-shaped sandbox behind the dome.

An 1872 rebuilding program gradually replaced the Ten Brinck firebox with a Bonnet that had slightly more area and tube heating area increased to 203.03 sq m (2,185 sq ft). Of the first thirteen engines produced by Cail, 12 remained in service on the PO-Midi n 1934 and all received SNCF class IDs (040 A 101 a 113) in 1938.


Class 1114/040 114/040C 114-133 (Locobase 21012)

Data from "040 nñ 1 114 a 1 133 du PO" on the WikiPO website at [link], last accessed 24 April 2022.; and Maurice Demoulin, TraitT pratique de la machine locomotive ... Tome Premiere (Paris: Baudry et Cie, 1898), pp. 134-135.

After the first 80 Orleans entered service in 1863 (Locobase 11272), the railway produced an updated design with "fundamental modifications". One of those mods was a Ten Brinck firebox (see Locobase 11279 for a full description of this excellent gas producer). Like the earlier engines, all of the motion, including the eccentrics, lay outside of the drivers.

Many had two sandboxes. Photos show that some placed both drums behind the dome, others sat one ahead and one behind the dome.


Class 1134/040 134/040C 134 (Locobase 21015)

Data from "040 nñ 1 114 a 1 133 du PO" on the WikiPO website at [link], last accessed 24 April 2022.; and Maurice Demoulin, TraitT pratique de la machine locomotive ... Tome Premiere (Paris: Baudry et Cie, 1898), pp. 134-135.

Class 1179/040 179/040E au F 179 (Locobase 21017)

Roman Sanchez, "Tout feu, tout flamme ! #4", posted on 29 July 2021 on the

Train et Tcologie, XIXe-XXIe siFcles website at [link], last accessed 24 April 2022. Cockerill works numbers 1282-1311 (road 1179-1208) in 1882; Fives-Lille works numbers were 2606-2635 in 1884 (road 1209--1238), and SACM-Belfort works numbers were 3928-3947 (road 1239-1258)

Bonnet modified the Ten-Brinck smoke consumer to make it easier to retrofit to existing locomotives. According to Sanchez, its redesign deleted the hopper, substituting a regular fire door,which also reduced the cost. Like the earlier engines, all of the motion, including the eccentrics, lay outside of the drivers.

Otherwise, this largest production run changed little from the the 040-141s shown in Locobase 21016.

Class 1179/040 179/040E au F 179 (Locobase 21018)

Data from "040 nñ 1 141 S vers 1 258 S du PO" on the WikiPO website at [link], last accessed 24 April 2022.

By 1929, 59 of the 108 locomotives from these two classes had been fitted with new boilers that contained supeheaters.

Those upgraded were 1141S-1143 S, 1147 S, 1152 S, 1154 S, 1158 S-1159 S, 1162 S, 1166 S, 1168 S, 1171S, 1180 S, 1183 S-1184 S, 1187 S, 1190 S, 1191S, 1195 S- 1201S, 1205 S, 1207 S, 1209 S, 1211S, 1213 S- 1217 S, 1221S-1223 S, 1225 S- 1230 S, 1232 S, 1239 S, 1244 ,
