Data from "New Express Engines, Dutch State Railways," The Locomotive Magazine, Vol V (September 1900), p. 134 and Du Bousquet and Herdner, "On the Question of Locomotives for Trains Run at Very High Speed (Subject XII for discussion at the Sixth Session of the Railway Congress,", Bulletin of the International Railway Congress Association, XV, No 9 ( September, (1901), p. 2083.. Beyer, Peacock works numbers were 4075-4089 (1899), 4165-4184 (1900-1901), 4267-4296 (1901), 4321-4350 (1902).
According to Wikipedia' listing of Dutch State Railways classes, these were the first of a bigger design to handle heavier passenger trains. They had Belpaire fireboxes and large-diameter, internally finned Serve boiler tubes. Their nickname was "Overkoker", which Wikipedia translates as "Boil Over". Locobase imagines that these locomotives had to be handled carefully?
