Therails on the ]\Ietropolitan Line were originally laidon the mixed-gauge principle, the rails themselveshaving steeled surfaces given to them ; but thesebeing found to be not of a very durable character,were gradually replaced with others of solid steel,which, although much more costly to lay down, whilst the second and third classes carry as manyas eighty persons respectively, and very frequentlymore. The mode of lighting the carriages is bygas, which is carried in long india-rubber bags,within wooden boxes, arranged on the tops of thecarriages, and extending from one end to the otherof each set of vehicles composing the train. Thesegas bags, says the writer of the work above re-ferred to, are weighted on the top, and, as the.

Within the last fewyears, the broad-gauge rails have been taken up,and only the narrow-gauge is now used. So far as the engines and carriages are con-cerned, but little need be said here. The formerare fine, powerful machines, specially designed byMr. Fowler, the engineer-in-chief; and they arearranged either to exhaust the steam through thechimney in the ordinary way, or else to condenseit in tanks which are placed on cither side of theengine, and contain i,ooo gallons of water—asupply suftkient for the double journey.
