The continued growth of long-distance railway traffic led to a major expansion along the station's west side starting in 1887. The work involved rerouting Cardington Street over part of the burial ground (later St James's Gardens) of St James's Church, Piccadilly, which was located some way from the church. To avoid public outcry, the remains were reinterred at St Pancras Cemetery. Two extra platforms (4 and 5) opened in 1891, and four further departure platforms (now platforms 12–15) opened on 1 July 1892, bringing the total to fifteen, along with a separate booking office on Drummond Street.
