History
Based on the 75 ft (22.86 m) M1 the early H-series cars improved on the design, notably by enlarging the operator's cab and using a single-handle controller. Over the programme revisions were made to the designs and each production model in the H-series improved on the last. The H5s were the first to use "chopper controls" and were also the first cars with regenerative braking along with air-conditioning systems. The H6s replaced the original red G-class cars and no further H-Series orders were made. A prototype then-new car T-series was built by UTDC in 1990–1991, and evaluated by the TTC. By the time the TTC was ready to order new cars in 1992, UTDC had been sold to Bombardier. Bombardier then constructed the new car order, which would add new technology such as AC propulsion to a similar platform based on the predecessor H-cars.
48 cars based on the H1 model were built and used for the Expo Express in Montreal, Quebec, for Expo 67. 108 modified H6 cars were produced for the Ankara Metro by Bombardier in 1996–1997.

Famous quotes containing the word history:

“I think that Richard Nixon will go down in history as a true folk hero, who struck a vital blow to the whole diseased concept of the revered image and gave the American virtue of irreverence and skepticism back to the people.”
—William Burroughs (b. 1914)
“All history is a record of the power of minorities, and of minorities of one.”
