Dutch State 4-4-2 Locomotives in Netherlands

Class Details by Steve Llanso of Sweat House Media

Class 2000 (Locobase 2670)

Data from 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

Building on the Beyer, Peacock 4-4-0s of a few years earlier, these Atlantics permitted a much bigger firebox. Family resemblances include side rods outside of the frame, outside bearings on the trucks, outside leaf springs over the drivers, prominent truck equalizing bar. But the longer firebox gave the engine a more powerful appearance. They pulled the Flushing-Venlo (130 miles) mail trains, averaging 55 mph on the 48 miles between Flushing and Roosendaal.

Roger Hennessey (nsc.chelt@talk21.com) comments that they were not very successful because they were unsteady. A letter from Charles A Brantsen in Railway & Locomotive Engineering's November 1901 issue (Vol. 14, #5), p.475 commented on their heavy-footed riding qualities: They were "... simply terrors to the permanent-way department, an army of platelayers having to follow in the wake of every express drawn by one of these engines. Accordingly they were temporarily withdrawn from service 'until heavier rails had been laid down.' This is now about a year ago, but they still remain shut off from the outer world in some obscure corner of Tilburg sheds, patiently waiting till their days of exile will be over."

A PS to the same letter added that reliable sources informed him that the locomotives would be back in service in Summer 1902: "In the meantime," Brantsen reported,"they are having new journal bearings fitted to them, as they were, previous to their withdrawal, continually heating up. The engines will run between Amsterdam and Emmerick, that being the only line built strong enough to carry these engines."
