Class 1 (Locobase 14588)

Data from DeGolyer, Volume 57, pp.148-163. See also "American Locomotives Recently Built for Export," Railway Magazine, Volume 39, pp. 372- Works numbers were 43111-43120 in March 1916; 43199-43208 in April; 44878-44885, 44922-44923, 44932-44935 in January 1917; 45049-45052, 45060-45067, 45089-45093, 45125-45129 in February; 45280-45286; 45334-45340 in March.

These little saddle tanks burned coal bricquettes. RM singled out a feature of the firebox that it particularly liked. Each radial stay consisted of a "radial bolt ...screwed into the inside firebox sheet." At the upper end, the nut was seated in a die-forged stirrup and that was tapped into the outer sheet. The play in the stirrup allowed the nut to rise as the crown expanded.

Why was this "strong, light design" a benefit? It used ordinary stay bolt taps and offered "a minimum amount of obstruction to the free circulation of water over the firebox crown. In this respect it is preferable to the various forms of T-irons and crown-bars which have been extensively used in the past."

24 (ex-5) was sold to Redbourn Iron & Coal after World War One and 25-26 (ex-6 and 7) went to the Belgian State Railways.

29 (ex-10) took on several road numbers and a name (Haren) and was ultimately sold to F N Pickett & Son.


Class Waril (Locobase 15939)

Date: January 07, 2011 01:53PM", at the Narrow Gauge Railroad Discussion Forum, [link],178234,178719, last accessed 8 January 2015. See also "Dockyards" in The New Werner Twentieth Century Edition of the Encyclopaedia Britannica (Akron, Ohio: Volume 7, The Werner Company, 1907), p. 270.

"The proximity of Deptford yard to the capital is of great importance, in the convenience it affords for receiving from this great mart all the home manufactures and products which may be purchased for the use of the navy. It is the general magazine of stores and necessaries for the fleet, whence they are shipped off, as occasion requires, to the home yards, the outports, and the foreign stations, in store-ships, transports, coasting s.loops, lighters, and launches, according to the distance they have to be sent.

"The management of Deptford naval store yard is now merged in that of the victualling yard, a most complete establishtuent of its kind. Till 1869 this management comprised a naval captain superintendent, with a master in the navy as his assistant. Under them a storekeeper, a store receiver, an accountant, au inspector of stores, and their respective staffs, conducted the administrative duties of the place. In 1869 the Board of Admiralty, in accordance with the recommendations of a departmental committee, abolished the offices of captain superintendent and master attendant, and placed the establishment under the civilian management of the storekeeper. 'The naval superintendents were appointed for five years, and after that titne were withdrawn to make way for others. The superintending storekeeper is appointed as a permanent officer, aud under him experience is accumulated and applied in all the manufactories and other business depart-ments of the yard. The manufactures conducted by and for the Government at Deptford comprise biscuit making on such a scale as to supply, with the yield of the victualling yards at Gosport and Plymouth, biscuit enough for the whole navy, and also chocolate making, mustard 'flaking, flour grinding, and the operations of a large cooperage. Most of the salt beef required for the navy is salted and put up there. Deptford may be called the heart of the victualling service. From its stores are shipped the whole of the con-signments required for replenishment of depots abroad, as well as the requirements of the other two victualling yards in England, except that at the last-named the supplies of biscuits and flour are provided on the sput. The number of men etnployea at Deptford necessarily varies. During war upwards of a thousand men are required. The space occupied by the victualling yard is about 19 acres. There is a river frontage of 1700 feet, and a mean depth of 1000 feet."
