Life Time Of A Locomotive

The iron liorse does not last mueh longer than the horse of flesh and bones. The ordinary lit'e of a locomotive is thirty years.' Some of the smaller parta requíre renewal every six months ; the boiler tubes last five years, and the crank axles six years; tires, boilers and lire boxes from six to seven years; the side frames, axles, and other parta, thirty years. An important advantage is that a broken part can be repalrftd, and does not condemn the whole locomotive to the junk shop ; while, when a horse breaks a leg, the whole animal is only worth the ilesh, fat and bones, which amount to a very small sum in this country, where horse üesh does not flnd its way to the butcher's shambles.
