Life of a Locomotive.
Some careful experiments which have been made in England prove that the life of a locomotive is about 500,000 “train miles.” In other words, that a locomotive of the latest improved pattern will run 500,000 miles before wearing out so as to be useless. In making this run of 500,000 miles, the fire box will have to be renewed three times, the wheel tires five or six times and the crank axles from three to five times.
