Data from "Old Belgian Tank Locomotives", Locomotive Magazine, Volume XXI [21] (15 February 1915), p. 31. Works numbers were 222-227 in 1873.
Station shunters of good size, this sextet originally entered service at the Quartier Leopold (Gare de Luxembourg) and retired in 1912 from the Schaerbeek depot. They "always gave excellent service".
