ST. PANCRAS STATION: THE INTERIOR.
Without question, the London terminus of the Midland Railway Company can challenge favourable comparison with any other station in the world. The station itself is not so extensive as the Great Eastern terminus, in Liverpool Street, but it is said to have the largest roof, unsupported by a single pillar, in existence. This roof of glass and iron, upheld by girders of an uncommon kind, which are in keeping with the style of the hotel, is no less than 243 feet broad and 690 feet long, covering in its huge span four platforms, eleven lines of rails, and a broad road for cabs. To the left of our picture, the west side, are the booking offices, and from this side the trains depart, the eastern platforms being reserved for arrivals. This triumph of construction was designed by Mr. Barlow.
