Construction history edit

The 25 locomotives of the first batch were originally delivered as 0-8-4 Engerth locomotives by Le Creusot in 1856–1857,[2] with the fleet numbers 0.164 to 0.188.[3] Due to the inherent inconveniences of the Engerth system, particularly in case of derailments, the decision was taken to rebuild these engines into locomotives with separate tenders, at which point they were also renumbered 0.501 to 0.525.[4] Additionally the adhesive weight could be increased from 39.3 to 45.5 tons. The rebuilding work was carried out in the Est Company's workshops at Épernay from 1860 to 1868.[2]

The wide firebox of the Engerth machines necessitated it to be placed outside of the wheels and therefore resulted in a large overhang, which had to be compensated on the rebuilt machines with a counterweight of 1,100 kg (2,425 lb) in the front of the engine.[5][6] The counterweight was reduced to 800 kg (1,764 lb) in the following 38 machines of the subsequent orders from 1866 to 1872, and then finally omitted on the later series from 1880.[5]

The subsequent batches were ordered with some differences from various manufacturers from 1866 to 1884.[1]
