Three-cylinder Locomotives.

To the several interesting types of passenger locomotives introduced on the group railways at Home during recent months there has now been added a new series of engines of the three-cylinder single-expansion type, with 4–4–0 wheel page 21 arrangement, constructed in the Darlington shops of the London and North Eastern line. These locomotives are intended for hauling express passenger trains other than the Anglo-Scottish fliers, and each engine bears the name of an English or Scottish county.

The principal dimensions of this new type of locomotive are as follows:—Cylinders, 17 inches diameter and 26 inch stroke; boiler length 11 feet 4½ inches, diameter 5 feet 6 inches; heating surface, 1,397 square feet; boiler pressure 180lb. per square inch; total wheelbase 48 feet 5¼ inches; total length 58 feet 8¾ inches; total weight of engine and tender in working order, 118½ tons; coal capacity 7½ tons, water 4,200 gallons. The engines are painted in the standard green of the L. & N.E. group, and they present a remarkably spick and span appearance in traffic.
