Abstract:
Concrete has been used in building metropolitan underground railways from the beginning of such construction. It was used in the structure of the Metropolitan District Railway in London, authorized by Act of Parliament in 1854, construction beginning in 1860, the successive extensions not being completed until 1884. It was used in backing the haunches of the brick arches, in the footings of masonry sidewalls, in backing behind the sidewalks as the timbering was removed, and later in the sidewalks themselves and in the inverts.
