Grande Compagnie du Luxembourg No. 102 to 107 and 115 to 122

Belgian Railway types 23 and 24

Belgium 1871 14 produced
Type 24 Locomotive Magazine, June 1922

Although they were no Engerth supporting tender locomotives, these 14 0-8-0 freight locomotives were also called “Engerth du Luxembourg”. The explanation for this is that apparently all powerful freight locomotives were called “Engerth” in France and Belgium at this time. They were the first eight-coupled locomotives in Belgium and were intended for heavy freight service on the line between Namur and Arlon that led towards Luxembourg. Their builder was Charles Evrard with his Compagnie Belge pour la Construction du Materiel de Chemins de Fer.

The first six were built in 1871 and were numbered 102 to 107. They had a round-topped firebox that was located in an overhanging position behind the last driving axle. Numbers 115 to 122 built in 1872 had a Belpaire firebox that was mounted above the last driving axle. Additionally, they had a somewhat larger firebox and less tube heating surface and weighed less. The state railway took over these batches as types 23 and 24 in 1873. Later they were used on secondary lines in the Hainault region. Their withdrawals were between 1891 and 1903.
