The vehicles of the series 141 P were the most powerful steam locomotives of the SNCF of the type Mikado with the wheel arrangement 1'D1 '.
history
Soon after it was founded in 1938, the SNCF was in dire need of locomotives for mixed service. The decision was made in favor of a Mikado design that could again be used as a universal locomotive , derived from the 141 C of the Compagnie des chemins de fer de Paris à Lyon et à la Méditerranée (PLM), which were built as 141 PLM 1 to 680 from 1918 to 1934 . At the time this series was designed, over 1000 Mikado locomotives with a tender were already in service in France, and development began in 1913. Due to lack of time without production and testing of an advance locomotive , the Division des études des locomotives de la SNCF (DEL), which was responsible for the conceptual design of the SNCF 150 P , SNCF 240 P and SNCF 241 P , relied on this proven design. The DEL was responsible for the development of future steam locomotives for the young SNCF. The newly built series began with the designation P at SNCF. For specifications , however, were against the model of PLM significant changes in frame thickness, boiler construction, vapor trails, suspension and automatic loading of the grate. Most of the improvements in the design of this series were again due to André Chapelon . Commissioned between 1941 and 1946, the commissioning of the last series machine was delayed until 1952. Initially, the companies involved were involved in building the DR series 44 for the German occupation authorities.
technical features
As is customary in France for high-performance locomotives, the locomotives had a four-cylinder compound drive of the De Glehn type . In contrast to the template of the PLM and the later SNCF 241 P, the high-pressure cylinders were arranged on the outside and the low-pressure cylinders on the inside. The inner low pressure cylinders work on the cranked second coupling axle, the outer high pressure cylinders on the third coupling axle. A slide valve made it possible to supply the low-pressure cylinders with high-pressure steam when starting up or when there was a large power requirement. The control of the Walschaerts type was carried out for the high and low pressure cylinders together with a control shaft.
The Bissel steering frame - consisting of a first and a second axle - corresponds to the Italian type Zara .
The locomotives were coupled with a four-axle bogie tender of the type 34 P, 36 P or 36 Q, each equipped with a steam engine for a stoker of the type HT1, built by Stein et Roubaix. These types of tenders were coupled with the SNCF 150 P and SNCF 241 P. With an empty weight of 37 t, they held 34 m³ or 36 m³ of water and a coal reserve of 12 t or 9 t.

business
The 141 P were in service in the network regions (Régions) Sud-Est , l'Est and l'Ouest . The first deliveries were made in the Sud-Est region , but were only in operation here until 1955. At this point in time, 17 machines had already been temporarily put on hold for repairs, as enough SNCF 141 R were available. The locomotives were in the Est region in the depots Châlons-sur-Marne , Chalindrey , Chaumont , Noisy-le-Sec , Mulhouse (Île-Napoleon), Nancy (Heillecourt) and Sarreguemines and in the Ouest region in the depots Le Mans , Rennes , Montrouge , Granville and Argentan stationed.
In terms of performance, the machines exceeded expectations and could have been approved for a higher top speed. The locomotives proved their economic efficiency. Compared to the American and Canadian-made SNCF 141 R commissioned from 1945, they were about 30 percent cheaper in consumption. In terms of maintenance and repair, however, it was inferior to these simple two-cylinder locomotives. After a short period of service, they had to give way in many places to the 141 R, which had over 1,300 units, and the change of traction.
In the Ouest region , the series was retired by October 1968, where it was last stationed in Argentan. The last 141 P ever was retired in the Est region in February 1969. All machines were scrapped.
Models
The elegant locomotives were reproduced in the model by numerous manufacturers, for example MINIATRAIN, La Maison des Trains, Jouef , Rivarossi - later both continued by Hornby - and Lemaco (see also).
