This copolymer has proved particularly suitable for wire and cable insulation, with many grades being rated at 155°C for 20 000 h continuous exposure. It is extensively used in electrical systems for aircraft, underground railways, computers, telecommunications installations and heating circuits. Because of its toughness combined with its heat and chemical resistance it also finds use for lining pumps and valves and other equipment for the chemical industry and for laboratory ware. 

Spasm of the ciliary muscle may impair accommodation and is associated with severe headache. Long-lasting miosis, associated with eye pain, was a notable clinical sign in the Tokyo Subway (underground railway) terrorist attack with sarin and the same was true of the sarin attack at Matsumoto (Nohara and Segawa, 1996). 

The attack with sarin on the Tokyo Subway (underground railway) has added considerably to our knowledge of the clinical effects of sarin vapor. The symptoms observed were largely as expected, namely cough, difficulty in breathing and tightness of the chest, bradycardia and eye pain (Masuda et al., 1995 Nozaki et al., 1995 Ohbu et al., 1997) (see Chapter 13). 

This view of the Main East haulageway at Tunnel Quarry shows boxes of contact mine fuses being despatched from No. 5 District onto the low-belt which will carry them to the north face of the underground railway platform. 

Special attention has been given to microorganisms present in the air of underground railways in London and New York in the first quarter of the century [3], and more recently in the Hungarian capital of Budapest [10].

The Soviet scientists G. Flerov and K. Petrzhak attempted an experimental verification of this hypothesis. But how to establish that fission of the uranium nuclei was really spontaneous Random neutrons of cosmic rays getting into the laboratory could distort the results of experiments. This is why one autumn midnight of 1940 Flerov and Petrzhak went down to one of the deepest stations of Moscow underground railway. There, tens of metres under the surface of earth, the harmful effect of cosmic rays could be escaped. The same night they obtained the final proof of the existence of a new type of radioactive transformations, namely, spon-... 

The first underground railway in the world was opened on January 10,1863 in the City of London, operating with steam locomotives. The first line with electric traction and a three-rail system was built in 1890. The four-rail system, still in use today and consisting of two insulated conductor rails and two running rails, was introduced in 1903 in the course of electrification of the old steam tracks. The Metropolitan Company, responsible for a part of the track, used ac, while the District Railway preferred dc as a consequence of the connection with the American railways. This dispute came before a British arbitration tribunal in 1900. The problem of corrosion of public supply lines by the returning current fi om electric train...

The VAL is a hght underground railway running on several sites in France (for example LiUe, Toulouse, Orly-Val and CdG-Val) and abroad (for example Chicago, Taipei and Turin). 

In this chapter, we describe the architectural evolution of safety computers in the railway signaling sector, namely at Ansaldo STS. CSEE-Transport, a compaity estabhshed in 1902 to work the underground railway signals in Paris, became Ansaldo STS in July 2007. However, CSEE-Transport is better known as a world leader in high-speed signaling. 

Ansaldo STS is also the supplier of underground railway signaling systems (Copenhagen, Paris, Shenyang, Milan, etc.), which use the same technology. 

ERTMS is a Enropean standard, which is currently being deployed, whilst applications for automatic underground railways are spreading around the worid. The evolution of safety platforms will continue in order to meet the needs of these new applications, which often exceed 100,000 lines of Ada code. Increasing the size of the software will also lead to increased complexity and hence new requirements for the CSD. 

In the field of guided transport, applications concerning automatic underground railways have, of course, similar requirements. They often demand more stringent performance than for high-speed trains. Improved performance is a result of technological change, but improvements in the architecture principles are also essential. 

On 20 March 1995, Aum Shinrikyo launched a further sarin attack, this time on the Tokyo underground railway system. About 24 litres of sarin of only 30 % purity were released from polythene carrier bags by cult members. 

London Underground is a wholly owned subsidiary of London Regional Transport the Statutory body responsible to the Government for the provision of public transport services by Bus and Underground railway opened in 1863 and the worlds first deep level electric railway opened in 1890. The network serves 273 Stations and comprises nine lines The District, Circle, Metropolitan and East London are subsurface railways, the Bakerloo, Central, Northern, Piccadilly, Victoria, Jubilee and Waterloo and City (transferred from British Rail ownership in 1994) are deep level tube railways although all lines except the Victoria have surface sections outside Central London.
