Within the New York City metropolitan area, the airport system—which includes John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport (located in New Jersey), Stewart Airport and a few smaller facilities—is one of the largest in the world. The Port of New York and New Jersey, which includes the waterways around New York City and its metropolitan area, is one of the busiest seaports in the United States. There are also three commuter rail systems, the PATH rapid transit system to New Jersey, and various ferries between Manhattan and New Jersey. Numerous separate bus systems also operate to Westchester County, Nassau County, and New Jersey. For private vehicles, a system of expressways and parkways connects New York City with its suburbs.
Tower Subway is a tunnel that runs under the River Thames that was first used as one of the first underground railways in London. The tunnel is located between Tower Hill on the north bank and Vine Street, off Tooley Street on the South Bank. The line was operated over a short distance using a stationary car and single carriage, and a cable system. The whole system gained parliamentary approval in 1868 but at first no contractor was willing to build it due the difficulties experienced during the construction of the Thames Tunnel. This was overcome when James Henry Greathead tendered for construction and the tunnel was built by Peter W. Barlow between 1869–1870 using a cylindrical tunnelling shield they designed.
The Tower Subway was eventually superseded by Tower Bridge which was built a few hundred yards downriver in 1894. In 1898, the Subway was closed and was then used by the London Hydraulic Power Company for hydraulic tubes and water mains. It survived a World War II bomb blast which resulted in at point of impact the radius reduced to 1.2m and was found to still be in excellent condition. Nowadays the tunnel is used for mains and telecommunication cables. (Full article...)
From the mid 1840s until 1857, Barlow was chief engineer for the Midland Railway, after which he set up his on consultancy in London. Between 1862 and 1869 he was the consultant engineer on the Midland Railway's extension from Bedford to London, designing St Pancras station and the 240-foot (73 m) wide cast iron and glass train shed roof over the platforms, the widest unsupported arch in the world at the time.

A60 stock trains operated on the surface and sub-surface sections of the Metropolitan line from 1961 to 2012 and 1938 Stock operated on various deep level tube lines from 1938 to 1988.

Continuation of the West Cross Route northwards under the roundabout was cancelled leaving two short unused stubs for the slip roads that would have been provided for traffic joining or leaving the northern section.
