The locomotives of the series 3500 of the former French railway company Compagnie du chemin de fer de Paris à Orléans ( PO ) were Tender - steam locomotives with the wheel arrangement 2'C1 '. The four-cylinder compound locomotives were fundamentally rebuilt in the 1930s according to the plans of André Chapelon and assigned to new classes.
History and description
In 1909, the PO ordered Pacific type locomotives for their topographically not too demanding routes, particularly Paris – Bordeaux and Bordeaux – Irun . The machines, which were based on the 4500 series delivered from 1907, were intended to enable an increase in the speed and weight of the express trains operating there . The main difference to the 4500 was the 100 mm larger diameter of the drive wheels .
The Société Alsacienne de Constructions Mécaniques (SACM) built the locomotives 3501 to 3520 in 1909 and the machines 3351 to 3570 in 1912. The 3521 to 3550 were built near Fives-Lille in 1910, the Anciens Établissements Cail delivered the 3571 to 3589 in 1914. The after the outbreak of the Locomotive 3590, which was completed at Cail during the First World War , was confiscated by the German army and used for military purposes.
Whereabouts
In 1929 Chapelon converted the No. 3556 into a much more powerful and at the same time more economical machine (new company number 3701). The success of this prototype prompted the PO to convert locomotives 3501 to 3520 based on the model of the 3556 in 1932 and to refer to them as the 3700 series from then on. The other locomotives were also converted accordingly in the following years; After completion, 25 of them remained with the PO, 23 went to the Compagnie des Chemins de fer de l'Est (EST) and 20 machines went to the Compagnie des chemins de fer du Nord (NORD).
