Overview

The series of 250 engines, numbered 141-001 to 140-250 were built in 1921. The 140 Cs were renumbered 141 C 001 to 140 C 250 by the SNCF in 1938 and ended their career in the West of France at the end of the 1970s.

Design

The engines were capable of a speed of up 100 km/h. Their light weight per axle made them capable of hauling both passenger and goods trains on most of the Chemin de Fer de l'État's network and of the former Chemin de Fer de l'Ouest. Due to the need of a simple to operate and solid locomotive, the Chemin de Fer de l'État even went to choose the pressure of the firebox (or "timbre" in French). The pressure was 12 kp/cm² or 12 "hectopièzes" (old units of measurement, 1.2 MPa in modern units), this enabled to machine to develop an output of convert|1540|hp|abbr=on at 60 km/h and convert|830|hp|abbr=on at 100 km/h. It increased the "timbre" in 1932 to 14 kp/m² to obtain a power of convert|1700|hp|abbr=on at 60 km/h and convert|1160|hp|abbr=on at 100 km/h.

141 C 50 was rebuilt at Sotteville (Rouen) in 1928. This depot was built by the British in 1840 and was the largest of the Chemin de Fer de l'Ouest (then Etat). There it received new Renaud type valves, saving 9.8 % coal. It also received a Kylchap exhaust.
