Great Central, Fjur-Cynndcr, 4-6-0 Tyfc Fast Freight Lo Recent Tendencies in British Locomotive Practice PART 1 Description of Important Designs; Piston Valve withRelief and By-pass Features; Mechanical Lubricator By E. C. Poultney IN the present article the writer proposes to illustrate anddescribe some typical recent locomotives built for serviceon British railways which indicate the tendencies of mod-em practice. Perhaps one of the most striking features is the large usemade of either three or four cylinders, and of these the threecylinder arrangement seems to be rapidly gaining favor. Onthe North Eastern three-cylinder 4-4-2 type express locomo-tives have been in sen-ice since about 1910, and the same cyl-inder arrangement has more recently been extended to 4-6-0and to mineral traffic locomotives of the 0-8-0 type on thisrailway. The Great Northern has also adopted three cylin--ders for both 2-6-0 and 2-8-0 typ>e freight locomotives, andq
