Шаблон:Short description Шаблон:Infobox locomotive Est 501 to 562 was a class of 62 French Шаблон:Whyte locomotives for express passenger service, built in 1878–1886 for the Chemins de fer de l'Est.
Construction history
The first series Est 501–510 was built 1878–1879 at the workshops of the Chemins de fer de l'Est in Épernay.Шаблон:Sfnb The general design of the frame was carried over from the earlier Crampton locomotives, but with an additional coupled axle replacing the second leading axle. The first few machines had a round-top firebox which protruded down between the two driving axles,Шаблон:Sfnb while the later machines of this series had a Belpaire firebox which extended over the second coupled axle.Шаблон:Sfnb The boiler tubes had a length of Шаблон:Cvt and the steam regulator was of the Crampton type with the steam pipes running down to the cylinders externally.Шаблон:Sfnb The Cylinders were placed horizontally on both sides between the double longerons of the frame with the connecting rod directly driving the second driving axle. The driving wheels had a diameter of Шаблон:Cvt.Шаблон:Sfnb
The second series, comprising Est 511–542, was built in 1881–1882Шаблон:Sfnb in two subseries at Cail (1881) and Wiener Neustadt (1882).Шаблон:Sfnb The diameter of the driving wheels was reduced to Шаблон:Cvt, and also the firebox was changed to one with a rounded top which also extended over the second coupled axle.Шаблон:Sfnb The reversing mechanism of the Gooch valve gear was rearranged.Шаблон:Sfnb Also the cylinder size was reduced to Шаблон:Cvt on the machines Est 523-542.Шаблон:SfnbШаблон:Sfnb
The third and last series, Est 543–562, was built 1884–1885.Шаблон:Sfnb The main differences compared to the preceding Est 523-542 series was the lengthening of the boiler and boiler tubes, which now had a length of Шаблон:Cvt.Шаблон:Sfnb Also the cylinder size had been increased to Шаблон:Cvt.Шаблон:Sfnb
In 1888, two locomotives of the first series, Est 508 and 509, were fitted experimentally with dual drum Flaman boilers with a boiler pressure of Шаблон:Cvt.Шаблон:Sfnb Due to the increased weight the leading axle had been replaced by a two-axle outside-frame bogie. Although these machines apparently did not meet the expectation, they still remained in service until 1925.Шаблон:Sfnb
In order to increase the available traction, 48 locomotives of the series 511–562 had their driving wheels reduced from Шаблон:Cvt diameter down to Шаблон:Cvt, which was sufficient to pull the local trains on the main and secondary lines. The locomotives were also renumbered to the range 2511–2562.Шаблон:Sfnb
The series Est 501–510 used a two-axle tender with a capacity of Шаблон:Cvt water and Шаблон:Cvt coal and weighing a total of Шаблон:Cvt, while the series Est 543–562 used a two-axle tender with a capacity of Шаблон:Cvt water and Шаблон:Cvt coal and weighing a total of Шаблон:Cvt.Шаблон:Sfnb
