ed. Tank engines are particularly useful for localand suburban traffic; and, in fact, without themit would practically be impossible to run scoresof trains in rapid succession into any Londonterminus between 8 and 10 oclock in the morn-ing and between 5 and 7 oclock in the evening,at which time many thousands of workers areproceeding to the city or leaving it. Tank engines are sometimes used for compa-ratively long journeys, but not non-stops. Anewspaper and mail train leaves Paddington at5.30 a.m., and arrives at Bristol at 8.25, calling 4_4_2at five stations. It is a pp with 6 feet 8 inches driving-wheels. Much might be said of the development ofthe tank engine if space would allow, but it wouldbe at the expense of other matters that must notbe omitted; and a tank engine after all is onlyan ordinary locomotive minus its tender. If onewill only keep ones eyes open during a railwayjourney it will not be difficult to discover the chieftypes. The position of the wat6r tank is subject to

In thefirst the water tanks are placed at the sides ofthe boilers, rising from the frame plates over thedriving wheels; in the second the water is storedin a well underneath the foot-plate; and thesaddle-tank rests upon the barrel of the boiler inmuch the same manner that a saddle is placedupon a horse. Omitting those engines of special design tomeet some particular requirements of the lineupon which they work, we find that the tankengine largely resolves itself into three maintypes, viz. (l) After coupled; (2) Front coupled;(3) Six coupled. Having said so much we mustleave the illustrations to make the matter perfectlyclear. We will close the chapter with a referenceto a tank engine of very special design. TheGreat Eastern line has to deal with an enormoussuburban passenger traffic entering into LiverpoolStreet termi
