État 42-001 to 42-020 comprised a series of 2-8-2T steam tank locomotives operated by the Chemins de Fer de l'État.
Design
Conceived in parallel with the 140 C series, the 42-000 locomotives utilized simple two-cylinder expansion and incorporated robust fireboxes akin to those found on the 140-100 series. Although the fireboxes delivered strong performance, other parts were modest in scale, including relatively small cylinders measuring in diameter. The choice of small driving wheels was deliberate to facilitate swift acceleration, aligning with the operational requirement to efficiently haul heavy steel passenger cars.
Construction
This batch of twenty locomotives, numbered from 42-001 through 42-020, was manufactured by Fives-Lille and allocated to the Batignolles motive power depot. Although their design dates back to 1913, their construction was postponed due to World War I, with deliveries completed in 1923 to the Chemins de Fer de l'État.
Service
Intended for service in the western suburbs of Paris, these engines underwent modifications in 1930 enabling push-pull functionality. This allowed control from a driving cab situated on a Voiture État à 2 étages carriage via compressed-air piping, streamlining turnaround times at terminals. Upgrades included fitting a smoke deflector and enclosing the cab. After the creation of SNCF in 1938, they were renumbered as 3-141.TC 1 through 20.
With the electrification of the Réseau Saint-Lazare, these locomotives were transferred to Brittany. The last units operated out of St-Brieux depot and were later leased to the Société générale de chemins de fer et de transport automobile (CFTA) following the regauging of the Réseau Breton lines from metre gauge to standard gauge. The final unit of the 141.TC series was withdrawn from service in 1971.
Preservation
One example, number 42-019 (SNCF 3-141.TC.19, Fives-Lille serial 4328 built in 1923), is preserved by AJECTA at the Musée vivant du chemin de fer located in Longueville, Seine-et-Marne. It has been recognized as a Monument historique.
