Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . p; Yorkshire Railway Mr. George Hughes, the mechanicalengineer of the Lancashire & YorkshireRy., has applied a superheater I0-8-O locomotives built at the Horwichshops of the company, which differs insome essential particulars from other su-perheaters hitherto in use. In the ordinary type of superheaterthere is usually a steam header dividedinto two separate chambers by a partitionOne of these is for saturated and theother for superheated steam. The latterHows from the header, through cast ironor welded steel pipe, down each side ofthe firebox to the cylinders. This arrange-ment is effected by placing the large tubesin horizontal rows. In the Horwich superheater the tubesare arranged in vertical rows, and the up-per header holds nothing but saturatedsteam, while the ends of the superheatertubes drop down towards the bottom ofthe smokebox, to connect with two su perheater headers, one on each side of thesmokebox, and each of these is in directcommunication with a cylinder.
