Data from L Derens"The Dutch Rhenish Railway and Its Locomotives"," The Locomotive Magazine, Volume XXVI [26] (15 October 1920), pp. 229-230. The first nine came to the Rhenish State in 1889, but later batches brought the total to 50 by 1903. The first 9 were delivered in 1889 without the extended smokebox, 359-379 arrived in 1891, and 380-399 in 1892.
Derens wrote that these were the first four-coupled-and-bogie engines to run in the Netherlands and the first such British-built to be sold to the Continent. Hauling international trains as far as Oberhausen in Prussia, they generated considerable interest among the Prussian State Railways. On a rising 0.33% grade, the design was expected to pull 200 trailing tons at 48 mph (77 kph) and 56 mph (90 kph) on the level.
Placing the inside cylinders as close as possible to the centerline (2 ft 0 1/2 in between centers) granted "the greatest possible length for the crank axle bearings." The valves had to be mounted at outward leaning angles.
Edwin Boer, whose drawings can be found on the website [] (14 March 2004), comments that the SS found the locomotives too long for their turntables and sold them to the HSM.
NB: The stated tube heating surface area was 1,097 sq ft (101.97 sq m) from 241 1 3/4" (44.45 mm) tubes, each 11 ft 4 1/4 in (3.46 m) long. Like many Continental railways, the figure came from the tubes' inside (fire side) diameter. When added to the 104 sq ft of the firebox, amounted to 1,201 sq ft (111.58 sq m) of evaporative heating surface area. Locobase calculates the surface area using the external (water side) diameters, which was the norm for virtually all North American and United Kingdom locomotives.
