HILLSIDE WORKSHOPS

TWELVE "0” LOGOMOTIVEf ORDEREu r FIRST OF THEM FINISHED Constructive work at. the Hillside Railway Workshops is actives One of the orders is for the building of twelve new locomotives of the “C” class for shunting work, to - replace! the “F ■” class locomotives, now obsolete. The first of the dozen- is now completed and tested—as a matter of fact, it has drawn’ a trainband’ it is to bo iii regular service in a;- few- days. It has a handsome • appearance, and its design embraces some of j the most modern; features in locomotive construction. - ■’ These “ C ” locomotives are'of the 2—6—2 type, with two cylinders, to which, superheated steam is distributed by piston valves actuated by Walschert’s valve gear. Ample boiler and firebox proportions are provided. The boiler barrel has an outside diameter of 4ft 3in, its length being 20ft. it contains twelve superheater flue • tubes 54m diameter outside, and seventy-nine fire tubes If in diameter outside. The firebox is of a round-topped type, arid has a grate area of twenty-four square feet. A tumbler . grate' is fitlbd, and the ashpan is of the Hopper type, with, bottom cleaning doors. Feed is supplied to boiler by a top feed, service, and two Ross (pop 'safety valves are fitted. The principal dimensions are as follow : Gauge of rails, 3ft Gin. ' : > Cylinders (2) ; Ki n -.

Goodall drawgear between engine and tender. ■ , Ragonet pneumatic power revere iug gear. Pneumatic cylinder, cock operating .... gear. - - , : Automatic continuous . air brake and straight air brake for shunting. Generally this locomotive _ represents a skilful and interesting piece of designing work, a feature being the general accessibility) of all parts.
