London Transport International Services Limited (LTIS): International Telephone and Telegraph (ITT) Industries: Reports and Manuals

This series contains manuals and reports concerning the Scarborough Light Rapid Transit system in Canada, its software and hardware design and testing procedures. ITT Industries is a leading manufacturing and engineering company, one of the world's leading international industrial corporations, operating around the world. This series contains records of business and projects carried out with ITT Austria and Standard Elektrik Lorenz (SEL) Canada, a division of ITT Industries of Canada Limited. Standard Elektrik Lorenz (SEL) was the West German branch of the USA based ITT company formed in 1958 on the merger of the companies Lorenz, Schaub and Standard Elektrizitaetsgesellschaft, but operated mostly independently from ITT. SEL Canada, ITT Industries of Canada (established 1981) was based in Don Mills, Ontario. In 1984 London Transport International was approached by SEL to carry out a verification of the safety analyses of the automated transit control system they had developed: SELTRAC. SELTRAC was a computer-based train control system which was designed with the functionality to be applied to virtually any fixed guideway transit system. In 1985 LTI tested the application of the ITT SELTRAC system to the Scarborough Rapid Transit (RT) system. Scarborough RT is a public transport metro line in the Scarborough district of Toronto, Ontario, Canada, one of the rapid-transit lines of the Toronto Transit Commission (TTC). The SELTRAC system was also selected for the 'Skytrain' in Vancouver which opened in 1986. In 1986/1987 SEL merged with French companies Companie d'Electricite and Acatel with the new company being known as simply Alcatel and the German part as Alcatel SEL AG. SEL took with it to Acatel (Canada) the SelTrac product (which was modernised and still on the market in 2006).
